Re: [meteorite-list] Appropriate terminology?
I would advocate that we on the list clarify the use of the term 'Martian meteorite' or 'lunar meteorite' as those bits of Mars or the moon transported here to Earth descending through our atmosphere as we've been using these terms all along. This is as versus 'Mars meteorite' or 'Moon meteorite' as those specimens found on Mars or the Moon. Any one know an already established convention??? Otherwise, the semantics gets muddled...

Re: [meteorite-list] Appropriate terminology?
Rosie, You are correct, although meteor refers to the visual phenomena associated with the passage of a meteoroid through the atmosphere, not to the object causing it. What Rubin and I proposed is that impacts onto the moon or other airless bodies can still result in objects that we call meteorites despite the lack of any meteor before the collision. I don't think that Joseph's suggestion of using moon meteorite to signify meteorites found on the moon as opposed to lunar meteorite to signify meteorites that came from the moon is a good one. It's still highly confusing. Fortunately, 99.99% of the time, collectors and scientists don't have to make this distinction, as we have virtually no specimens of meteorites collected on other bodies. Until we do, I don't think we need a special term. We can just say Hadley Rille and Bench Crater, asteroidal meteorites found in lunar soils collected by Apollo astronauts. jeff At 10:25 PM 1/15/2003, Rosemary Hackney wrote: I always thought that if it was in space it was called a meteoroid.

Frank, etc., Nope. You didn't understand all of what I said. The first part is right: we don't care if there was a meteor or whether the body doing the accreting had no atmosphere. Once the impactor survives landing, it becomes a meteorite. If it becomes incorporated into a rock as a xenolith, it is still a meteorite (e.g., Brunflo and the Osterplana fossil meteorites found in earth rocks, and). BUT, if the rock containing the clast itself becomes a meteorite by being ejected from its parent body and landing somewhere else, then the clast is no longer a meteorite... it's just a clast in a meteorite. We had to adopt this complex rule because otherwise we'd have to give a meteorite name to every asteroidal xenolith found in an asteroidal meteorite. The second part of your question should have been phrased: On another note, I was wondering what, if any, differences might be expected in the fusion crusts on meteorites found on Mars as compared to meteorites found on Earth?

My answer is, I don't know. jeff At 04:32 PM 1/15/2003, you wrote: Hi Jeff and all, In other words, if I correctly understand this, on another moon, asteroid or airless planet, the part of a meteoroid that survives impact on another body becomes a meteorite without an intervening meteor stage; (unless of course, it may have previously grazed an atmosphere ala the Gran Teton fireball of the 1960's). And once it becomes a lithified part of the impacted body, it becomes only a xenolithic clast.

Just a challange.. Interseting challenge, I'll take it! Most of us have rarer meteorites than these two from the moon! Do you remember, there is a type of meteorites called howardite, supposely comming from the soil of Vesta. In these meteorites, it is not so uncommon to find some small black inclusions. If I remember well they are related to carbonaceous meteorites... So I have something rarer (based on location of find, tkw and type) than these two from the moon!!

[meteorite-list] Re: possible lunar: High Quality Picture
Good evening Mohamed and Friends, Sorry Mohamed. While I am always cautiously optimistic about possible Lunar meteorite finds I am afraid that I must agree at this point with my learned colleagues. The photomicrograph seems to reveal that your find is not likely a lunar meteorite. I was most interested in seeing the white clast material under magnification. Having now seen it, it does not appear to be similar to the clast material I have seen in authenticated Lunar specimens. Don't give up your quest for meteorites because of a few failures though. As seasoned meteorite hunters will tell you, meteorwrongs are all part of the process. I have read some really good advice directed your way by List Members in the past couple of days. I am sure that much of it will be helpful to you. Keep up the search and you will eventually find your meteorite.

Mohamed, This is my last attempt to appeal to your sense of mathematical reality. You wrote: No, this rock in particular is not magnetic at all. I have another suspected lunar breccia (http://www.alifyaa.com/meteorite/ln3/) where the bulk is very little magnetic but not the clasts. ... I thank all those who replied, this seem the first find that gave me some hope, let us wait and see the results of tests. I want you to consider the comparative numbers of lunar and Martian meteorites that have been found vs. all other types combined. I'm not sure what the most up-to-date statistics are, but somewhere in the ballpark of 1 in 500 meteorites is lunar or Martian. It is extremely unrealistic to assume that your very first meteorite find will be of this type. You would need to find roughly 346 meteorites before you'd have even a 50-50 chance that one of them was either lunar or Martian. This doesn't even factor in the comparitive difficulty of recognizing a lunar or Martian rock vs. recognizing a chondrite. Chondrites without fusion crusts can still be recognized fairly easily in most cases; not so lunars and Martians. Given that you haven't found a single chondrite yet, it is presumptious in the extreme to think that you have magically acquired the skills necessary to find something far far rarer. Show me a chondrite. Until you do, it is ridiculous to mention achondrites. --Rob __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

Hello List, In the early morning of 17th of January 1999, 4 years ago tomorrow! a loud bang and a big hole was discovered in 18 thick ice on a small lake in Atwater, Minnesota. The hole was about 3 feet in diameter and no one could say for shure what had caused it. Later some others were found on the same lake. Divers went down, a turtle, earthly stones and some garbage was found, but no meteorite (at least not in the winter of -99??). I have seen dozens of articles about these holes, but personally so far, NO picture of this enigma... Since there are many reports of unexplainable holes on ice all over the northern hemisphere, it would be interesting to compare the looks and morphology of such holes to one another. So, does anyone know of pictures of these holes, either on the web, or elsewhere?? Was there in the end any firm conclusion of what had caused the holes, btw? Regards, Bjørn Sørheim PS.

While I am always cautiously optimistic about possible Lunar meteorite finds I am afraid that I must agree at this point with my learned colleagues. The photomicrograph seems to reveal that your find is not likely a lunar meteorite. I was most interested in seeing the white clast material under magnification. Having now seen it, it does not appear to be similar to the clast material I have seen in authenticated Lunar specimens. Don't give up your quest for meteorites because of a few failures though. As seasoned meteorite hunters will tell you, meteorwrongs are all part of the process. I have read some really good advice directed your way by List Members in the past couple of days. I am sure that much of it will be helpful to you. Keep up the search and you will eventually find your meteorite.

Re: [meteorite-list] Dinosaurs Experienced Climate Changes Before K-T Collision
What acid rain do you refer to? This is an impactor, not a volcanic eruption. Acid rain would have to be supplied with large quantities of nitrous and sulfuric compounds in order to cause any damage. So far as I know, no significant (if any) acid spikes are noted from any deep ice corings for any recent impact event (last 30,000 yrs) so this is not a reason for lack of dinosaur (note that I have never mentioned any other type of fossil bone) fossils close to the K-T Boundary.

The main item that no one seems to point out in lit is the fact that mammals could have caused the dino decline.

Re: [meteorite-list] Dinosaurs Experienced Climate Changes Before K-T Collision
The bones would not have survived the acid rain long enough to be fossilized. Same goes for bones in the process of fossilization. What acid rain do you refer to? From the sulfuric acid. This is an impactor, not a volcanic eruption. Acid rain would have to be supplied with large quantities of nitrous and sulfuric compounds in order to cause any damage. Exactly! Would billions of tons of sulfur thrown up into the atmosphere suffice? I believe so. The impactor landed in the Yucatan Peninsula, which just happens to be a sulfur-rich area. So far as I know, no significant (if any) acid spikes are noted from any deep ice corings for any recent impact event (last 30,000 yrs) so this is not a reason for lack of dinosaur That may be, but we're talking about an event from 65 million years ago, not 30,000 years ago. I've appended the 1994 press release below about the sulfur. I don't think this meteorite list was in existence then, so you may have missed it. Ron Baalke Don Savage Headquarters, Washington, DCDecember 28, 1994 (Phone: 202/358-1547) Diane Ainsworth Jet Propulsion Laboratory, Pasadena, CA (Phone: 818/354-5011) RELEASE: 94-219 SULFUR-RICH ASTEROID SITE HOLDS CLUES TO DEMISE OF DINOSAURS NASA scientists now believe it was the sulfur-rich atmosphere created in the aftermath of an immense asteroid collision with Earth 65 million years ago that brought about a global freeze and the demise of the dinosaurs. The impact of this large asteroid hit a geologically unique, sulfur-rich region of the Yucatan Peninsula in Mexico, according to planetary geologist Adriana C. Ocampo and atmospheric scientist Dr. Kevin H. Baines, both of the Jet Propulsion Laboratory's Earth and Space Sciences Division, Pasadena, CA. They estimate the impact kicked up billions of tons of sulfur and other materials and was between 10,000 to 50,000 times more powerful than the comet Shoemaker-Levy 9 impact on Jupiter last July. The researchers and colleagues, Dr. Kevin O. Pope of Geo Eco Arc Research in La Canada, CA, and Dr. Boris A. Ivanov of the Russian Academy of Sciences in Moscow, have co-authored a paper detailing the global atmospheric impact of this asteroid collision at Chicxulub, Mexico, in the latest issue of Earth and Planetary Science Letters. We estimate that this asteroid was between 10 to 20 kilometers (6 to 12 miles) in diameter and its collision on Earth brought about total darkness around the world for about half a year, Ocampo said. But more importantly, persistent clouds generated by the impact on this geologically distinct region of sulfur-rich materials caused temperatures to plunge globally to near freezing. These environmental changes lasted for a decade and subjected organisms all over the world to long-term stresses to which they could not adapt in such a brief time span, Pope added. Half of the species on Earth became extinct as a result. The researchers based their work on computer models of the impact and atmospheric effects, studies of the crater geology and extensive fieldwork at a rock quarry located 360 kilometers (223 miles) south of Chicxulub at Albion Island in Belize. Fragments bearing the unique characteristics of the impact were found in this area. In studying the sites and modeling the resulting changes in the biosphere, the scientists discovered that it was the specific geological location of the impact in a region that is rich in sulfur materials that created catastrophic climate changes and led to the downfall of the dinosaurs. If this asteroid had struck almost any other place on Earth, it wouldn't have generated the tremendous amount of sulfur that was spewed into the atmosphere to create such a devastating, worldwide climate change, Baines said. On impact, the asteroid hurled some 35 billion to 770 billion tons of sulfur high into the atmosphere, along with other materials. The NASA team, in collaboration with Dr. Alfred Fischer of the University of Southern California, recently discovered rocks in Belize -- some the size of a small car -- that were blown out of the crater and landed south of the Chicxulub site. The boulder deposit in Belize also contained fragments of glass that were created by the melting of rock when the asteroid crashed into Earth, Ocampo said. Spherical fragments, known as tektites, were scattered and formed as the molten glass flew through the air and cooled. The tektites have been found in other regions near the crater, such as Haiti, Mexico, Texas and Alabama, but never in association with large boulders. Another important find at the Belize rock quarry was limestone with fossils dating to the early part of the Cretaceous. Fossils of this age don't belong in northern Belize, Ocampo said. Early Cretaceous fossils have been found

However, the exterior sure looks like fusion crust to me; similar to what I have seen before on a CK3. Very interesting. A couple of good microphotographs at 20X and 40X might be helpful too.
