Re: [meteorite-list] Impact Glass from Barringer Crater?
Mike - Impact melt glass at Meteor Crater is not pretty green or any
other pretty color, but dark melt beads, dark glassy impactites, and
the reddish brown glass that is common in typical oxidized
impactites.The spherules are tiny.
Go to: D. A. Kring, “Guidebook to the Geology of the Barringer
(Meteorite) Crater, Arizona”. LPI Contribution No 1355 (2007) -

I finally got myself a copy of Nininger's Find a Falling Star. It is
a great read, and insight into how doggedly he pursued his interests
against a steady stream of naysayers among those who might have been
inspired.
My immediate interest, is the passage on page 180, in which he
described a form of impact glass appearing in a variety of shapes,
including 'tear-shaped'. Unlike the typical solid glass Indochinite,
these seem to have encased a more non-homogenized interior, which
Nininger describes as 'spongy'. (In a sense of pourous, not flexible
or plastic) Here's a couple paragraphs from the book:
{begin quote}
Spurred on by discovery of the little metallic spheroids, I searched
and searched everywhere on all sides of the crater, on the rim and on
the plain beyond, examining everything more critically than ever
before, and one day made an even more exciting find.
I had stopped to examine a gravel pit dug into the crater rim by the
state highway commission. I found a few crushed bits of
yellow-green-brown slag; some showed a gray outer crust. I looked for
more, and soon picked up a small tear-shaped piece. It appeared the
same color as the light gray dust and gravel among which it lay, but
the rockhound's licking test revealed a dark greenish-gray color under
the dust. A canteenful of water dashed onto the gravel made it easier
to identify a number of such small bombs of various shapes and
sizes. All of these, when broken, were seen to be of a spongy
structure, but composed of brittle, glassy material. When I ground the
bits of slag on a sheet of carborundum cloth from my supplies in the
trunk of my car, and then held them under a pocket lens, they showed
small imbedded metallic particles, bright as chrome steel.
As I drove hurriedly back to the museum on Highway 66 to make a nickel
test, I puzzled over various questions. Could these be mere volcanic
cinders? Could lava fragments carry such imbedded metallic particles?
If these indeed were bomblets created by the impact of the meteorite,
why had they never before been discovered?
{end Quote}
In looking for additional info, I came across this:
http://www.impact-structures.com/2011/12/meteor-crater-arizona-discovery-of-impact-glass-spherules/
Not quite the same thing, but certainly intriguing! This would go
well along side my Wabar Pearls and Chicxulub spherules from Dogie
Creek, Wyoming.
I have searched some of the Tektite web sites hoping to find a source
for a specimen of the glass Nininger describes. I am coming up dry.
Does Nininger's material exist on the market? What is it called?
Any likelihood of tracking down those Barringer Crater spherules?
Any clarification will be appreciated.

When one goes about putting these together, one would generally work in at least a 24bit if not a 32bit space with a transparent background. I sick a whole bunch of processing power on the problem with a neural network looking for features that match-up. Once those millions of points are selected (through many hours of training and then automated iteration), my image processing software then has to warp, bend, fold, spindle, and mutilate the individual frames, stitching them together into an image that looks attractive on a flat 2D screen. When that's done, it needs to then have the bit depth reduced for end user consumption. That involves getting rid of the transparent background and filling that space underneath with some color. I have a few tricks that NASA/JPL folks may not employ. One of them is filling the background with pure Red (255,0,0), then another with pure Green (0,0,255), then another with pure Blue (0,255,0). Those then go through another pre-processing step of overlaying those and checking for each color pure color. Any area that flags for two of the three is suspect. Small areas that don't precisely line-up like that get flagged for manual revision. That step allows me to pull them into an image editor and quickly pixel-hack them together in a convincing way (although not scientifically valuable). I suspect they skip that step entirely and just fill the background with white and post it. Even with the current state-of-the-art, any time you have motion you have registration issues that can't be gracefully resolved. Mine show those artifacts around the rover itself, especially in the shadows. Creating panoramas from so many frames of a sphere and then unwrapping the sphere into 2D isn't an exact science.

The first NASA-produced view from the surface of Mars larger than one billion pixels stitches together nearly 900 exposures taken by cameras onboard Curiosity and shows details of the landscape along the rover's route. The 1.3-billion-pixel image is available for perusal with pan and zoom tools at: http://mars.nasa.gov/bp1/ . The full-circle scene surrounds the site where Curiosity collected its first scoops of dusty sand at a windblown patch called Rocknest, and extends to Mount Sharp on the horizon. It gives a sense of place and really shows off the cameras' capabilities, said Bob Deen of the Multi-Mission Image Processing Laboratory at NASA's Jet Propulsion Laboratory, Pasadena, Calif. You can see the context and also zoom in to see very fine details. Deen assembled the product using 850 frames from the telephoto camera of Curiosity's Mast Camera instrument, supplemented with 21 frames from the Mastcam's wider-angle camera and 25 black-and-white frames -- mostly of the rover itself -- from the Navigation Camera. The images were taken on several different Mars days between Oct. 5 and Nov. 16, 2012. Raw single-frame images received from Curiosity are promptly posted on a public website at: http://mars.jpl.nasa.gov/msl/multimedia/raw/ . Mars fans worldwide have used those images to assemble mosaic views, including at least one gigapixel scene. The new mosaic from NASA shows illumination effects from variations in the time of day for pieces of the mosaic. It also shows variations in the clarity of the atmosphere due to variable dustiness during the month while the images were acquired. NASA's Mars Science Laboratory project is using Curiosity and the rover's 10 science instruments to investigate the environmental history within Gale Crater, a location where the project has found that conditions were long ago favorable for microbial life. Malin Space Science Systems, San Diego, built and operates Curiosity's Mastcam.

Re: [meteorite-list] Nwa 7034
Well stated Jeff, one of the few times recently that we agree on issues. There is the fever to coin new terminology for this apparent unique stone (NWA 7034), which in essence is a breccia, but may not be a basaltic breccia. Everyone should calm down and wait until some further research information comes out in the forthcoming LPSC Meeting and the longer term research results that will come to light further on downstream. For those folks eager to get some time in on this naming issue, have fun with it, some of you are, patience to the rest of you. Ted On 1/26/13 1:27 PM, Jeff Grossman wrote: Meteorite group names are not invented by NomCom, and certainly not by NASA. The come from usage in the scientific literature. I think we have to remember why names like shergottite and nakhlite came into being. Scientists like to group similar things to help bring order to chaos. When you know next to nothing, you start by putting similar things together that you can study as a group. Once you learn more, relationships may be found among them. In this case, several groups plus a few oddballs seem to share a common origin: Mars. At this point, it doesn't really help anything to continue to generate trivial names for new groupings. The big advance has been made, and we can call them Martian meteorites. That means it is time to start treating all of these meteorites like we do geological specimens on Earth, using standard kinds of lithologic names. I know the old trivial names will die hard, and a term like shergottite will be with us for a long time. But there is no good reason to continue creating new trivial names. ALH 84001 need only be called a Martian pyroxenite (assuming this is the best rock name for it). If 10 more of these are found, they only need to be called Martian pyroxenites; there is no need to define a useless new term like allanhillsites. The same goes for NWA 7034, which we can call a Martian alkali-rich basalt, or whatever Carl says it is. Note that nomenclature for lunar meteorites was never burdened with trivial names, as there were no famous historical falls or finds. After 30 years, lunar anorthosite meteorites are still just called lunar anorthosites. Scientists don't need to put them in a trival category like calcalongites to distinguish them from the basaltic kalahariites... this would only obscure what we know about all of these, and nobody will ever do it. So let's forget about inventing terms like saharanite or morrocanite or allanhillsite or whatever. (And while we're at it, let's consider forgetting about shergottite, chassignite and nakhlite.) They're unnecessary and useless to science.

Re: [meteorite-list] Nwa 7034
Dear Jodie - Selling on eBay is a dubious endeavor in itself. Scientists are not enslaved to the problems of economic gains for the unenlightened eBay flea marketeers. NWA 7034 has extremely significant scientific potential, possibly equivalent to or exceeds that of what the Mars Rovers have/are reporting. After all, having a Martian specimen in-hand that has water and Martian atmospheric signatures together with the potential for other science options that can be investigated via the in-depth array of Earth-based instruments, may far exceed most present expectations of Rover sensing. To quote me, patience. You can make more money if you have patience and allow the scientists to do their stuff. Do not sell short, invest for the long term.

Re: [meteorite-list] Primitive Achondrite Question
Well stated Jeff and I agree! Thank you. There is the thing about metachondrite terminology, but we shall leave this dead horse alone for the time being. Two of these unremitting classification issues in 3 days is much too much for me in one week, especially when my butt is tied to both of them. Ted On 12/5/11 7:02 PM, Jeff Grossman jngross...@gmail.com wrote: Type 7 is considered by most of those who use it to represent the highest degree of thermal metamorphism that a chondrite can experience without melting. As implied in that first sentence, some petrologists don't distinguish these from type 6. The term primitive achondrite is widely taken to be the next stage: you make them when a chondrite partially melts, and the process of crystal-melt separation begins. The primitive part says that the bulk composition is still fairly close to chondritic. But these definitions are not used by everybody, and you will get arguments about them. Clearly, the LL part of an LL7 classification for NWA 3100 is unlikely. O isotopes are below the terrestrial fractionation line, which basically rules it out. So it is not an LL7. Bunch has shown that the O isotopes are closer to CR chondrites. The hard part is the type 7 vs. primitive achondrite distinction. Bunch et al.'s 2005 and 2008 LPSC abstracts do not report anything in NWA 3100 that I take as evidence of melting or differentiation. So I don't see any reason to call these primitive achondrites, at least not based on these findings. I think the Bunch et al.'s conclusion that NWA 3100 is a CR6 is the best we have right now, but I think you still have to think of this as preliminary. Ted can correct me, but I think it was actually the nomcom that pushed for calling this a PAC, amid controversy on the committee.

Re: [meteorite-list] Al Hagg.. yawn?
of those things that fell between the sofa cushions and never got cleaned up? What is the status of the proposed reclassification in the Bulletin as an EL3? If it hasn't been done yet can anyone post an opposing view to keep the aubrite or other classifications alive? Maybe it hasn't been done because this relict meteorite is being called a fossil? I've heard of fossil living people but fossil meteorites - please let's not go there! Seems like there is more than one change being proposed on this page. Best IMO - one thing at a time, leave that battle for another time. IMO: The use of the word 'fossil' for dug up minerals according to this dictionary is obsolete: http://dictionary.reference.com/browse/fossil ...but beyond that for any it is extremely confusing to the commercial side of this especially to innocent buyers and hopefully the IMCA and other alike groups can regulate this if it sounds reasonable; since it is generally used to describe for living organisms or structures left by them, and therefore has associated with it an air of ancient life to the new collector, and there is no need to evoke this term any more than 'aubrite' if in fact that doesn't fit. As for 'paleo', it sounds like a $2 word for $0.06 per gram meteorite as well. Relict is a perfect term and even has precedence as it has been used throughout the Chicxulub studies to describe the tektites which in a similar fasion have been incorporated into sediment. So after reading the excellent and painstaking work by Drs. Ted Bunch and A. Irving, one has to wonder where Conan the Barbarian is just to come in and say: They are relicts and they are EL3's, further use of any other mentioned terms is immediately hereby suspended until noticed by the axe-wielding squad ;-), or an opposing view makes its stand in a peer-reviewed article.

Re: [meteorite-list] The Term Planetary
At a time in the distant past, NASA in its infinite wisdom made general reference to the solar system bodies as comets, asteroids, planets and their satellites, the latter referenced as planetary. Satellite is an ugly term and there are a lot of moons. So, to include our moon in the planetary fold seems reasonable, at least for meteorite people. Besides, the mostly accepted theory about the origin of the Moon is that it came from the Earth via impact and accretion of debris, so the Moon is a viable planetary body in its own right.

Re: [meteorite-list] CI1 meteorites and cyanobacteria
Well said!! On 3/5/11 4:19 PM, Marc Fries fr...@psi.edu wrote: Howdy all Here's my two cents, pure and simple - this paper is 110% bullshit. The filaments the paper addresses are nothing new. They are apparently amorphous sulfates formed from aqueous alteration of fine sulfides in the CI's. You can see that in the EDS spectra published in the paper - the predominant elements are sulfur, oxygen and magnesium. I.e., they are sulfates (e.g. Mg2SO4 + hydration water). Some silicon leaks into the measurement from materials behind one of the filaments. I happen to have two CIs on loan to me right now - Orgueil and Tonk. I have Raman spectra of the filaments found in both meteorites. They are sulfates. My personal Surprise Meter registers a whopping Zero. The argument is made that the lack of nitrogen in these fossils implies that they pre-date their residence on Earth. This argument starts with the assumption that the filaments are fossils, and then uses the non-detection of nitrogen to prove that they are fossils. This is a circular argument. Here's a more supportable hypothesis: no nitrogen was detected because they are not fossils, but rather exactly what has been known for decades - they are amorphous sulfate filaments caused by hydration of fine sulfides in the rock. This paper is a result of something I like to call the Lowell Effect. Basically, it is what happens when someone stares into an instrument expecting (or hoping) to see proof of life in the target. Percival Lowell did it through a telescope with Mars, drawing elaborate canals in his mind which indicated (to him) an advanced martian civilization. Certain other scientists do it with the Apex chert while peering through microscopes, and with hydrothermal graphite found in rocks from Isua, Greenland through all manner of instruments. The author of this paper pulled a Lowell Effect result out of his posterior after looking at CIs with an electron microscope. Where I come from, we also call that letting your hopes make a fool of your reason.

Re: [meteorite-list] Seeking Impact Materials
You ask a lot - there are good impactites offered at the Tucson show and on the internet. If you collected in the Raton Pass/ S of Trinidad road cuts along the Interstate or outlier sites from the Interstate in the region, I hope you had a knowledgeable field guide with you. Most of these exposures are slumped over. If you collected elsewhere in the region at a clean site, the fireball layer is difficult to resolve even if you are a trained geologist and even then, it is a ball buster to recognize the K/T layer. Clay layer look-a likes are intercalated with thinly bedded carbonaceous shales and coal seams and this sequence is typically meters thick on either side of the boundary.

Randy Korotev At 10:32 PM 2010-09-07 Tuesday, you wrote: Hi, Lunar Gang, and List, We have a situation here that needs straightening out. Escaping from the Moon is one thing. Getting to the Earth is another. Here's how it starts. An object is propelled off the lunar surface (doesn't matter how). As soon as it's no longer in contact with the force that impelled it, its speed can't increase. It can decrease, though, and it does. Lunar gravity will pull down on it, reducing its speed at the same rate it would gain if it fell. It goes slower and slower. Eventually, its speed will fall to zero and it will reverse course and start to fall back. UNLESS its starting velocity is above or at the Moon's escape velocity. It takes 2380 meters/sec to escape to the point 38,000 miles from the Moon's center to where the gravitation pull of the Earth and the Moon are equal. If the rock started with 2381 m/sec, it will get there moving at 1 m/sec, a crawl. After that, the important thing is: which way was it headed? Surrounding the Moon is a distorted spherical (parabolic) envelope with its pocket pointing directly at Earth that outlines that balancing point between the Earth's and the Moon's pull. It's called the Hill Sphere (for any body). The Hill Sphere, or equipotential point for the Moon, is at a radius of about 38,000 miles, still over 200,000 miles from earth. If a Lunar escapee has enough speed to reach the Moon's Hill Sphere and cross over, it will be under the control of the Earth's gravitational field. The Moon has only 1/81.3 of the mass of the Earth, so the balance point between them is much closer to the Moon than the Earth. Oh, if it was going very fast, it could escape the Earth too, but the odds against that are great. No, that rock is dam lucky to have made it to the Translunar Gravitational Equipotential Point for its flight. In general, since Lunar escape velocity is low compared to the Earth's, if a rock just barely escapes, by the time it crosses the Border, it would be moving very slowly, almost standing still. From the viewpoint of the Earth, it's like someone carried a rock 'way out there and while standing still far from Earth, dropped it. Like so many borders, once you cross it, you're in another jurisdiction. The Moon no longer has any say in what happens to the rock that crosses the Hill Sphere Border. Slowly at first, it begins to fall toward Earth, but it moves faster and faster, eventually acquiring (up to) 11,233 meters/sec, plus any starting speed, blah, blah... Will it curve and swerve and head straight for the Earth's central spot? No, not often. There are a variety of outcomes and few of them will get a rock to land on Earth. Many will end up co-orbiting the Sun along with the Earth and will eventually tangle with the Big Mother Planet again. Some, that are headed more or less toward the Earth to begin with will scream past in an asymptotic pass, whipping around the Earth, changing direction and picking up speed, in a home grown version of the gravity well maneuver. They will tossed far and gone, in a gentler version of what Jupiter does to anything gets near it. But only if they miss... Some of those headed our way, a small percentage, will actually strike the Earth, or come in at a steep angle. They might survive to the ground... or they might not. A few, we lucky few, will graze the top of the Earth's atmosphere tangentially, in a flat trajectory roughly parallel to the surface of the planet, at about zero degrees of altitude (relative to us). They will be moving between 11,186 meters/sec and 13,466 meters/sec and their chances of landing are As Good As It Gets. That's the simple view from Physics 101. It turns out to be more complicated, however. NOW, we have to turn the question around and look at it from the Moon's and the Rock's perspective. If you're a rock looking to get the Earth, what's the best way to leave home? That will determine what happens to you in the long run. So, imagine you're an indecisive rock staring at the black Lunar sky... If you aim for where the Earth is NOW, it won't be there when you arrive. so which way do I go?!

Re: [meteorite-list] Cyanobacteria in meteorites?
Dear Darren and Eric - having worked on ALH 84001 years ago and having been involved in research/management of the NASA -AMES Exobiology Program, I am a skeptic of fossil life in 84001 or any other Martian meteorite recovered to date. However, the finding of water on Mars and the recent discovery of methane does give promise. We know that Mars had water oceans at one time, although we do not know how long the water reservoirs were available to promote simple life. It took 100s of millions of years to accomplish that feat on Earth in the form of cyanobacteria, about 3.5 billion years ago. The main problem with fossil life in carbonaceous chondrites is contamination. With respect to Orgueil and contamination, Paul Pellas told me a long time ago that most of the museum's Orgueil collection had been stored haphazardly in boxes in the same drawer with various French coal samples - not good. Even though Murchison is a fall, there may have been sufficient time for the transfer of cyanobacteria or other simple organisms in the soil to nutrient-rich, water-bearing Murchison specimens. The best sample for fossil life study could be Tagish Lake - those samples that were immediately collected and carefully treated to avoid most forms of contaminates. My bottom line is that meteorites are a poor harborer of life in any case.

Re: [meteorite-list] Pairing discussion/questions
Jeff - your statement from below Also, don't overlook the fact that Antarctic meteorite have proven to be vastly more valuable scientifically than NWA meteorites is misleading and somewhat biased. Meteorites of the various classes are nearly equally represented in the Antarctic and Desert collections. Some classes are better represented from the desert collections, for examples, brachinites, angrites, Martians and the Antarctic collections have more acapulcoites, aubrites, and some carbonaceous. But, the number of samples doesn't really matter. The number of scientific publications 10X means little in terms of scientific significance. The use of Antarctic specimens is largely biased if you consider the following: 1) NSF funded Antarctic samples are more easily obtained for research compared with trying to obtain samples from collectors, dealers and repository collections and they are usually prepared for instant study (thin sections, cleaned, diced, boxed, etc.). 2) NSF has put pressure on various institutions to either publish more on the 1000s of Antarctic meteorites, obtained with NSF funding, or lose support for future Expeditions. 3) There is considerable bias among some researchers to not use Desert samples for political reasons and the lack of exact find locations (Nomads do not use GPS instruments, not that this means much). Some museums are extremely biased against dirty desert meteorites and will not let them in the door, thus depriving researchers for easy access to samples for study - a very prominent Federally funded museum comes to mind. 4) The Japanese publish almost exclusively on their Antarctic meteorites, not Desert specimens. 5) More and more research papers deal with both Desert and Antarctic samples and that tact is becoming more prevalent with time as bias diminishes and the reality of desert significance enters the mind set. I don't know how you factor that into the numbers game. 6) A shot at more valuable scientifically - if not for the valuable lunar samples collected from the deserts, we would know much less about the Moon - see the Korotev web site on Lunars. And, and we know a Hell of a lot more about Mars from Desert Martians - See Irving web site on Martians. Bottom line - geography has little to do with a meteorite's significance.

Is there any initiative taken by you, the Australian scientists, to modify the unhandy laws?

Re: [meteorite-list] exact Carolina Bay crater locations, RB Firestone, A West, et al, two YD reviews, 2008 June, 2009 Nov, also 3 upcoming abstracts: Rich Murray 2009.11.14
Patience Darren. Listed below are the various scenarios presently considered to account for the YD impactevent. When there is an absence of a crater, research needs to dig deeper, much like the position of the Alvarez group in the '80s before a crater was found for the K/T event. We know that airbursts have happened in the past (e. g., Tunguska), the questions are, how big have they been and how big can they be? What was presented prior to 2006 has little to do with present considerations concerning the origin of the YD event based on the efforts of 60 scientists from eight countries. Most of these efforts have focused on analyzing materials from sites that occur from California to the Caspian Sea, not speculating on potential origins. However, we do need to work the data with various impact options in order to see what are good and bad fits: (1) An extraordinary accretion of micrometeorites (Pinter and Ishman, 2008), which is inconsistent with YDB carbon spherule compositions and the huge amount of nanodiamonds found within the YDB carbon spherules. (2) Oblique impact (s) into the Laurentide Ice Sheet. This model does account for the absence of a crater and the lack of cratering markers. Also provides for the shock production of the many cubic and lonsdaleite (hexagonal) nanodiamonds found in the YDB. (3) Impact-induced aerial burst (s), e. g, Boslough and Crawford (2007); Shuvalov (2008). The lack of high shock pressures in an aerial detonation does not necessary preclude the formation of cubic and hexagonal diamonds. Maruyama et al., (1993) made hexagonal and cubic diamonds by a CVD process from a high temperature plasma atmosphere (13,000 °C) under conditions similar to those in an aerial burst. The Tunguska event is commonly accepted as the result of a near surface aerial burst and has many similarities with the YD event, including diamonds. (4) Comet grazing of the atmosphere (Drobysheski, 2009). Nearly tangent entry of a comet into the Earth¹s atmosphere with partial detonation and melting followed by escape of the unexploded nucleus into space. Has the net effect of an atmosphere-penetrating aerial burst followed by global fallout of detonation products. More work and time may give us a better understanding of the YD impact mechanism. In the meantime, I suggest that you are what needs to be peeled off the wall. Get a clearer focus on pertinent literature and on-going research - the upcoming AGU Meeting, with pro and con abstracts on the subject, is a good place to start.

These characteristics are inconsistent with known meteorites and suggest that the impact was by a previous unobserved, possibly extrasolar body. Okay, a review-- so far this impactor has been a 500 mile wide snowflake from the atmosphere of a supernova hitting at hundreds of kilometers per second. It has been an airburst over ice leaving no crater. It has left craters deeper than Death Valley in the Great Lakes. It has caused golden showers and a rain of diamonds that lasted for months. It shotgun-blasted iron particles into the tusks of mammoths. It has been a comet. It has been a chondrite, and all meteorites found by or through Nininger have been debris from it, so it was actually all types of chondrite and everything else Nininger collected. Now, it is an extrasolar lunar meteorite from the future. So, to sum it up, this 500 mile 10 mile very low-density metal and stone filled comet-asteroid supernova-produced lunar snowflake that struck at hundreds of kilometers per second did and didn't produce impact craters and left no marks except for the Great Lakes and thousands of very shallow overlapping, highly oblong pits exactly like craters from an impact event except for craters from an impact event rarely being very shallow, overlapping, highly oblong pits.

Yvonne and Tony Garchinski are the proud new owners of five
tiny meteorite fragments.
They also have a new windshield, after the space rock smashed into
their
Pathfinder three weeks ago.
I thought it was vandalism, for sure, said Tony Friday as dozens
of reporters converged on his west Grismby home. Who thinks a
meteorite
is going to crash-land on your car?
The golf ball-sized fragment is likely part of a larger meteorite
that lit
up the skies of southern Ontario
Sept. 25.
The fireball was first picked up by cameras operated by the
University of
Western Ontario's physics and astronomy department 100 kilometres
above Guelph
as it streaked southeastward at a speed of about 75,000 kilometres
per hour.
Scientists released that footage Oct. 7 and began searching a
12-square-kilometre area near Grimsby
where they thought the meteor fell.
Only after seeing the footage on television did the Grimsby family
realize their car-bashing
vandal might instead be an alien invader.
We filed a police report and everything, said a laughing Yvonne,
who held out the tiny silver and black space rock pieces for
reporters to see
Friday.
After reading up on the meteorite search, Yvonne called Phil
McCausland, an
astrophysicist at the University
of Western Ontario, who
verified the tiny rocks were out of this world.
They're probably the oldest rocks that you or I or anyone else are
every going to hold, McCausland said. it's pretty exciting.
The Garchinskis own the window-smashing space pebbles, but they've
agreed to
loan them to university researchers for three months.

Good job Sterling and correct. I have the Treasure--- movie in B W and the colorized version, that line was certainly given.

Dear Norbert, well stated. As a scientist and the retired Chief of the Exobiology Branch at NASA Ames, where much work has and is being done on ET organic chemistry, I agree with your assessment, although much of the cosmogenic organics are abiotic. However, with the right environment the abiotic soup could lead to biotic-life building blocks. Remember, Harold Urey and others did this back in the 1950's.

De Duve, who's everything else but a romantic dreamer and certainly not the kind of guy who's wasting his time with mental masturbation, comes to the conclusion that life must be kind of a cosmic imperative instead of a weird exception. But do me a favour, don't use the shortcut, i.e. don't Google it up, and avoid reading online summaries on Wikipedia and other sites - read the book from page 1 to 543, it's really worth the effort. After that you might want to re-read the studies on Murchison and other carbonaceous chondrites which do not only prove to contain a smorgasbord of various cosmogenic amino acids, but also nucleobases (the building blocks of RNA and DNA), water, and many other ingredients of life (as we know it), in addition to all the astronomic studies about planetary nebulae, the presence of water, PAH's, methane, and other carbon-based molecules in protoplanetary discs etc. pp. ... If you're still sceptic after all of that you might want to take a final step, look into the mirror and ask yourself if it's just your own bias that stops you from seing the obvious. I hope you don't take this as an offense as it sure isn't ment as one, but as someone who studied philosophical anthropology and the history of science it always takes me by surprise how many educated people don't understand the full consequences of the Copernican Shift. Don't get me wrong, of course they do know that Earth isn't the flat center of our solar system, galaxy, or universe. However, most did just exchange their geocentric view for a slightly modified anthropocentric view where man is still that special, unique, and most exquisite being: the Pride of Creation. And, of course, that also requires that life is unique, and restricted to that small planet Earth: the Cradle of Humanity. But, how scientific is that? It's pure human hubris, pitiful self-importance, IMHO. Don't get me wrong: I don't believe in aliens contacting us anytime soon - this is a enterily different affair and mainly a matter of time and space - but to deny the probability of life somewhere else in the universe is as stupid as the idea that planets around other stars are rare and exceptional (something that was often believed up to the late 20th century, also for obvious reasons), and as short sighted as Newton's assertion that meteorites can't come from space.

It proves absolutely nothing. How can an equation prove anything when none of the variables are known with any certainity? As Rob points out, one zero nullifies the whole silly thing. How about Ne; the number of known Earth like planets supporting life=0. If you want dumb equations, the creationists have a bunch of them that proves there is exactly one planet that supports life. I can make up an equation that proves the existence of mermaids, bigfoot, Nessie, unicorns, dragons, what imaginary being do you want to believe in? I'll write a formula to prove it's existence. I'll be easy, because I already know that life begets life. The Drake Equation misses the key concept in the alien debate; mainly how does abiogenesis occur? How does non living matter become alive? Once we figure out the mechanics of this most basic problem, then we can extrapolate about whether this seemingly miraculous event could happen more than once.

It has everything to do with proper chain of custody, legitimate nomenclature assignment, TKW figures, science and collector confidence. Just because a Moroccan dealer says something is a lunar meteorite does not make it so. Just ask the buyers who got ripped off in Tucson this year and the year before. There have been some very convincing lunar-looking Eucrites that have fooled some of the best. There was an embarrassing incident where a scientist claimed something was lunar before running all of the tests and it turned out to be a Eucrite. Many dealers had to recall the material after being in a hurry to put it on the market. To put things in perspective, Luniates are considered the top of the meteorite collectibles chain every since the article, Mining for Meteorites in the Smithsonian magazine stated so. Only advanced mineral collections incorporate Meteorite specimens. A mineral specimen is worth a fraction of its cost if the find location and history are not known. Advanced mineral collectors would be appalled by what has happened with Martian meteorites and self-pairings. One well-known dealer purchased material from a Moroccan who stated it was paired to one of our stones. We publicly objected to this dealer using nomenclature assigned to our stones so he sent a piece in for study. It turned out to be a completely new Martian meteorite that was almost lost to science. I would dislike seeing Lunar meteorites being treated the same as some Martian meteorites. Total known weights have been carefully recorded to this point and it would be a shame to lose control. I congratulate anybody who is able to acquire lunar material, have it Laboratory confirmed and pass the Meteoritical Society Nomenclature Committee for name assignment. It would demonstrate proper respect for some of the world's rarest material. Anything less is a disservice.

In any case, I don't think the reported O2 data are that discriminating between lunar and terrestrial. Some of the mineralogy looks OK, some does not. The plotted major oxide compositional data look impressive for lunar origin, but there are terrestrial mafic compositions that are just as lunar-looking. The hand sample surface is very irregular and looks more like a weathered terrestrial surface than fusion crust. Looks like a duck, walks like a duck, but it doesn't quack like a duck. My advice is to wait until it has been officially classified and/or Randy Korotev has looked it over before buying a piece. I also suggest that the Starchaser group do FeO/MnO ratios on olivine and pyroxene. These ratios are discriminating and can save everyone a lot of trouble.

Re: [meteorite-list] Higher than expected levels of sodium ... suggest that the dust clouds from which the building blocks of the Earth and neighboring planets formed were much denser than previously
Sounds like a good opinion to me - Ted Bunch On 6/21/08 9:48 AM, Steve Dunklee [EMAIL PROTECTED] wrote: Ionized particles in the early formation of chondrules would hold a charge. This charge would hold sodium vapor rather than allowing it to be driven away, much the way a sodium vapor lamp works. In effect the charge in addition to the low gravity would would tend to concentrate the available sodium , which would be deposited in the chondrules. You have to remember that most chondrules formed before the sun did ,so there was nothing to drive the gasses away which could allow higher than expected sodium in chondrules. Once the sun ignited any surface gasses would be driven away but any trapped sodium would remain. Higher sodium values do not prove higher concentrations of gasses at formation. If they were higher they would permeate the entire structure rather than be on the surface of the crystals, much the way salt concentrates on the surface of ice crystals in the arctic.

Re: [meteorite-list] Carancas crater
I am not sure why there is an argument about whether or not Carancas is an impact crater. Of course it is! In scientific terminology, impact pit is not acceptable. Let's review the facts: 1) The Carancas crater was produced by a hypervelocity impactor that excavated a deep hole and formed a raised rim of target materials (unconsolidated clastic debris). 2) Produced ejecta rays out 350 m from the crater 3) The event had sufficient shock energy to cause classic shock features in target quartz. 4) There is no size limitation for use of the term crater as long as the feature fits the accepted scientific constraints, e. g., formed by hypervelocity impact. LDEF (Long Duration Exposure Facility) flew in space for 5.5 years and studies of the facility skin showed thousands of craters as small as a few microns. Similar tiny craters have been found all over space shuttle vehicles. Apollo glassy spherules and rock samples show tiny impact craters as do several meteorite surfaces. In all of these cases, scientific reports used the term crater.

On the first page you will find the criteria for inclusion within this database (which is the most comprehensive and well-researched list on the planet).

The term impact pit is not listed in the Glossary of Geology (Jackson, 1997, 4th ed.), and is thus likely a loosely-used definition. Impact crater is listed in the Glossary and is defined as a generally circular crater formed either by impact of a projectile on a planetary surface or by an experimental hypervelocity impact of a projectile into solid matter...

It seems that some of the top scientists in the world think that it is a crater, perhaps you should enlighten them. Carancas is a crater, and I am not sure:), but I do believe that the impact of a meteorite created it, thus, I am still confused, but would that not tend to suggest that it is meteoritic? Adam, I think regardless of whether it is a common chondrite, the simple fact that it exists forces science to re-calculate its models for impact craters by chondrites. So Carancas is extremely important. I forsee papers written about Carancas for decades.

Carancas only produced a 13 meter mud hole squarely defining it as a pit. http://www.somerikko.net/old/geo/imp/listinfo.htm Pretty soon, the Carancas impact pit it will be no more than a depression in the ground with urine, fecal matter and trash in it.
