[meteorite-list] NP 08-1900, Meteorite Fall (?) Heats up Travelers
Paper: Newark Daily Advocate City: Newark, Ohio Date: Wednesday, August 22, 1900 Page: 5 AEROLITE FELL So Close To Travelers That They Felt Its Heat. (Danville (Pa.) Cor. Phil. Ledger.) Mr. and Mrs. D. E. Monroe, of Monticello, Sullican county, N. Y., who are making a tour in a carriage, were sufficiently close to an aerolite that last night dropped into the ground to feel its heat. They left Muncy about noon and were on their way to this city, where they intended to spend the night. They lost their way and about midnight found themselves on a lonely stretch of road remote from any dwelling. The spot, about ten miles from this place, is low and swampy and surrounded by wooded hills. Suddenly the sky was illuminated with a strange light, which the next instant lit up the entire landscape, giving it a brilliancy that was blinding. At the same instant a loud hiss or swishing sound struck the ears of a the man and woman and simultaneously it seemed, a blazing mass, not more than ten yards ahead, struck the earth. The roadway trembled under the mighty impact. The occupants of the buggy were nearly overcome by the appalling spectacle, while the horse stood trembling in its tracks. Mr. Monroe slighted from the buggy and led the horse to the spot where the aerolite had struck. The only trace of the celestial visitor was a volume of steam, which road from the spot, indicating the presence of water. Mrs. Monroe was made quite ill by the shock and the couple were obliged to stop at a farm house for the night. (PDF copy available upon request.

[meteorite-list] Tiny Bubbles
Hello List, I just ran into something new I don't recall seeing discussed here. While examining a piece of Mesosiderite NWA 1817 (which I believe might be paired with NWA 1878), I found a small cavity in an inclusion with tiny gas bubbles. The inclusion has a fairly dark matrix, but the little cavity is filled with a very clear, glass like material and several bubbles are clearly visible. Here is a link to some photos ranging from 0 to 100x.http://f2.pg.photos.yahoo.com/ph/skyrok99/album?.dir=/bd7dI took them through theeyepiece of the scopeso they're not the best, butyou can see the bubblesat the higher powers. Is this common and I am just running into it for the first time? Any background on this clear material and how/why the gas was captured there? Maybe an impact with a beanaroid sometime in its past ;-) Thanks for any feedback. Don Shervey
[meteorite-list] CV3 subtypes revised
Hello List, http://www.lpi.usra.edu/meetings/lpsc2004/pdf/1562.pdf I've read through many of the LPSC abstracts and this one seems to be significant in that it suggests a reconsideration of the subtypes of many CV3s. The authors utilized several methods to determine the subtypes of CV3 chondrites; Raman spectometry of organic material, a petrologic study of Fe zoning, and a noble gas study, rather than the TL sensitivity data of feldspar typically used for ordinary chondrite subtyping, and which was previously applied to the CV3s. They propose that TL sensitivity data is not applicable to aqueously altered CCs and they have redefined the petrographic subtypes of the common CV3s as follows: Allende - 3.6(TL - 3.2) Axtell - 3.6(TL - 3.0) Grosnaja- ~3.6(TL - 3.3) Kaba- 3.1(TL - 3.0) Mokoia - ~3.6(TL - 3.2) Bali- 3.6(TL - 3.0) Efremovka - 3.4-3.6 (TL - 3.2) Vigarano- 3.1-3.4 (TL - 3.3) Leoville- 3.1-3.4 (TL - 3.0) They plan to make further studies to validate this one.

[meteorite-list] Tiny Bubbles in NWA 1817
Hello Don and List, examining a piece of Mesosiderite NWA 1817...I found a small cavity in an inclusion with tiny gas bubbles. The inclusion has a fairly dark matrix, but the little cavity is filled with a very clear glass like material and several bubbles are clearly visible. Although your file is momentarily inaccessible, I wouldn't be too surprised to find such bubbles and glass-like material in NWA 1817, as it is described as having a plutonic, igneous texture (Met.Bull. 88, 2004). This mesosiderite will have crystallized from a molten magma (igneous) deep down in its asteroidal parent body (plutonic) and dissolved gases will have caused these bubbles when the material was transported to the surface by volcanic activity. Just a guess ... any comments? Best wishes, Bernd To: [EMAIL PROTECTED] [EMAIL PROTECTED] __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Why not oil /diamond blades for cutting meteorites?
I have tried oil and it works great. The cuts are smooth, fast and the blades last forever. However, the oil got imbedded in the meteorite cut surface and stained them (And possibly weathered them more also) and it made a huge (And I mean HUGE) mess that took me three months to completely clean up. Alcohol also worked very well and almost as good as oil and made no mess whatsoever and cuts were smooth and fast and do no damage to the meteorite. I have seen tons of sparks that went directly into the alcohol filled cooling pan and no evidence that I was about to start a fire. I ocasionally use alcohol on delicate things like Bensour for example but what I didnt like was that it made a lot of fumes and since most alcohol is piosenous I was worried about health concerns from breathing in the fumes and so dont typically use it. If you could devise a totally outside air supply to breath then alcohol in my opinion would probably be the best thing to use as a coolant. Maybe I could rig up my scuba regulator or something. As far as blades go I find that those meteorite blades dont last very long. The worst blade was ADVANTAGE which literally fell apart on me after 30 seconds. I couldent get over how bad those were. Theres bad blades and then there is advantage blades. I really give blades a hard going over so I would make a good tester for companies wanting to develop new blades. And I give a major thumbs down to Advantage blades. I use pro slicer blades and find them the best overall but they wont cut Iron (I have never been able to manage to cut Irons). There is a certain MK model blade that I like better but it cost more than twice as much and only lasts 50% longer so my opinion is that pro slicer is your workhorse blade and best value for the money. I buy them 50 at a time from the manufacturer to get the maximun discount. When I was a teanager we used to pick berries by the multiple 5 gallon can and brewed them in 45 gallon drums for 5 months (Mother nature loves me - the berries ripened in august and christmas was in december) and then ran off the wine that we brewed from it (And I was good, my stuff ignited and burned forever - just like the flame of vesta). After all those years I am not sure if I still have my distillery skills but for making high quality (And highly potent) meteorite coolant, I bet that if I tried really really hard, I could still manage to, ah, naww - I have better things to do. Most dealers use water as a coolant. After cutting I then bake my meteorites in the oven to get all of the water out as fast as possible. Cheers Dean --- Michael L Blood [EMAIL PROTECTED] wrote: Hi Elton and all, I am surprised no one who does more cutting than I has responded. It goes like this: Oil is fine for irons and even pallasites. Oil sucks for stones (and mesosiderites) because it discolors them horribly. (I do know one fine finisher that does use oil, but then puts all pieces in cat litter [the kind free of chemicals - this is important] for a minimum of 3 months to leach out the oil). Most do not have the time, space, patience and ability to delay financial return to utilize such a technique. I assume it works, as his stuff is dandy. So, since oil horribly discolors stone, this is why most use alcohol. Water (usually used with cutting solution added) is a no-no because water is the enemy of meteorites. Some use water and then immediately immerse the piece(s) in 99% alcohol which has a phenomenal propensity to absorb water, then put them in a stove with a pilot light where the humidity is near zero. The alcohol, which absorbed the water, is then evaporated rapidly. Be warned: alcohol is highly flammable, burns with a nearly invisible flame AND IS MUCH HOTTER than say a candle flame. When cutting with alcohol I always use as small amount as required, have a towel handy and running water near by. Still makes me nervous, but it is my preferred method - except in the exceptionally expensive pieces, where I use a new blade and NO cooling and toss the blade, such as with small Martian and Lunar specimens. In any event, I avoid oil at all costs. Best wishes, Michael on 3/19/04 11:21 AM, E. L. Jones at [EMAIL PROTECTED] wrote: Ok, I know this was covered recently but my archives are gone. I've been here years but, pretend I haven't and review for me the technical nuiances. Why is cutting with transformer oil not desirable for cutting/ windowing meteorites? Why do some recommend a carbide blade vs a diamond blade? Is this a distinction for iron vs stone samples? Any recommendations for cutting impactites such as Reis Seuvite? (Actually my 14 saw finally arrived after nearly two years and I wan't to cut something! I'd rather not be swapping out oil and ethanol each time I get in the mood to saw different materials.) Thanks, Elton
Re: [meteorite-list] Why not oil /diamond blades for cutting meteorites?
Hi Dean and List, It is crazy using alcohol in a saw that was not designed for it. You need a very low speed saw (1-300RPM) with the motor isolated from the cutting reservoir and fumes or else you are asking for a trip to the emergency room. Alcohol also destroys the rubber seals that protect your bearings and dissolves the grease in them causing premature saw failure. Oil does no permanent damage to meteorites so long as it is filtered on a regular basis. Literally every polishing operation I have seen uses distilled water. Using tap water is being cheap as it introduces chlorine into the meteorite creating long term reactions that break down the metal component and a few other minerals. Oil acts as a temporary sealant during the polishing operation preventing water from being absorbed into the specimen. The polishing operation removes most of the oil. A pure ethyl alcohol bath can be used to extract the rest of the oil trapped in the specimen. A final treatment should be to slow dry the specimen in a humidity free environment. We use a halogen lamp for this purpose. All specimens should be polished immediately after cutting because it reduces the surface area in which moisture can be trapped.

Hello Pierre, the hole is most probably a sinkhole, created by the collaps of a cave. I think limestone is very common in the area, underlying the soil.

[meteorite-list] Mars Exploration Rover Update - March 19, 2004
http://www.jpl.nasa.gov/mer2004/daily/3-19-04.cfm Spirit Status for sol 74 'Stub Toes' Won't Stop Spirit posted Mar. 19, 10:30 am PST Spirit began the morning of Sol 74, which ended at 6:25 a.m. PST on March 19, 2004, by completing an alpha particle X-ray spectrometer integration on the target Panda, inside the scuff on Serpent drift. Then Spirit placed the alpha particle X-ray spectrometer back down on the target Polar for a 30-minute integration. During that integration, Spirit took some images of disturbed soil with the panoramic camera, and acquired some ground temperatures with the miniature thermal emission spectrometer. Spirit then switched the tools on its robotic arm to the Moessbauer spectrometer for an hour-long integration on Polar. During that integration, the rover took some sky and ground measurements with the mini thermal emission spectrometer. Spirit finished its arm activities for the day by acquiring three microscopic images of Polar and three more of Panda. Starting around 12:35 p.m. Mars Local Solar time, Spirit made a direct drive of about six meters (19.7 feet) to another section of the Serpent drift complex, called Stub Toe. There the rover repeatedly scuffed the drift and advanced .15 meters (half a foot) in a series of five scuff and drives. After the five scuffs and advances were made, Spirit roved forward another 3 meters (9.8 feet) and then looked back over its shoulder using the mini thermal emission spectrometer and navigation cameras to analyze the damage. The rover continued along the Bonneville crater rim with a 16-meter direct drive, and then an auto-navigation drive for 9 meters (29.5 feet). Spirit completed a final set of drives to set up for a touch and go on sol 75 at around 2:10 p.m. Mars Local Solar time. The total amount of driving for sol 74 was an impressive 34.3 meters (112.5 feet). Spirit then took navigation camera and panoramic camera images of the drive directions for planning the sol 75 traverse. The rover acquired some mini thermal emission spectrometer reconnaissance images and then took a 30-minute siesta before the afternoon Odyssey relay pass. During that pass, Spirit used the mini thermal emission spectrometer to acquire a sky profile and ground temperature observations. On sol 75, which will end at 7:05 a.m. PST on March 20, 2004, Spirit will place the microscopic imager on a soil target and drive about 22 meters (72.2 feet) around the Bonneville crater rim. Spirit will also conduct atmospheric observations with the mini thermal emission spectrometer and panoramic camera. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Why not oil /diamond blades for cutting meteorites?
"a water based additive for fluids that permit cooling, lubrication and prevents corrosion of ferrous metals" Just a clarification I'd like to know, does the "for fluids" mean any fluid, like hexane, just polar solvents like water and alcohols, does it contain a surfactant that makes it miscible and otherwise effective both ways? Personally I's like to know if anyone has had a set up able to cut with Freon-11, or perhaps 113 (with a permit in some countries and mask, I believe it has few side effects although one for men to keep in mind might be that it shrinks (edited comment ... ask in private if you need to know). They have quite high heat capacities and might create your own personal sized ozone hole, though are still widely used throughout the world and I support their use with a solvent recycling-recovery system. I would think they would be fairly stable for short uses (i.e. covalent Cl), and heat them and presto solvent disappears, as if it was never there. If their boiling points are too low, another heavier CFC ... or Brominated one which I think have even higher heat capacities. Adam sounds like he is from Missouri (for very good reason), and it is good to hear he doesn't close his mind to advancing science...it would be quite foolish I think with thousands of liquids known that "alcohol" and "oil" and water are the only ones that work. Bill, the fume hoods at Menlo Park are waiting for you. I would just venture to say, DON'T CUT FRESH CARBONACEOUS METEORITES with any of these polar solvents and surfactants. Like, if I were to have amino acids in my meteorite, would I really want to extract them? I would never do that, and I've only cut one tiny window in a meteorite on a cheap tile saw and even I know that. But better the experts comment on that...
