RE: [meteorite-list] Genisis Crash
Yes, but the probe had a significant difference then a solid, smooth object. It was irregular in shape, and was probably light for it's surface area in respect to a glob of metal or stone. The characteristics through the atmosphere after losing cosmic velocity should be very different. The atmospheric drag on an object like this should me much greater, thus one would suspect that a meteorite that loses cosmic velocity should fall to earth much faster? What say you physics guru's?

[meteorite-list] metal-rich diogenite vs mesosiderite-C
Dear All, It seems, there is a problem with the class C mesosiderites and the metal-rich diogenites, which may just be fragments of the same meteorite shower. In the last Met. Bulletin 88, the following classifications and remarks are given: NWA 1982: an ungrouped achondrite not paired with NWA 1827 or NWA 1879 mesosiderite NWA 1827: mesosiderite (tentatively classified C) resembles a metal-rich diogenite... [but is] part of a large, heterogeneous mesosiderite containing sparse eucritic and diogenitic clasts In the abstract by T. E. Bunch et al. (2003) MAPS 39, no. 8 (Suppl.), p.A19, which is the same MAPS issue with the Bulletin 88, the authors conclude that NWA 1827 and NWA 1982 are paired and that they could be misidentified as metal-rich diogenite. So, at least for NWA 1982, we have a clear ambiguity between these two references. Best regards, Jörn -Ursprüngliche Nachricht- Von: David Weir [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 15.

I don't recall if Lafayette is actually on display right now, but the Smithsonian folks have an outstanding picture of it among the pics they keep in their office hallways. It is the most beautiful meteorite I've seen. The flow lines are pristine and damn near radially symmetric, with a high gloss even now. The story I heard was that it was found an unknown number of years ago in an unknown location, but turned up in a rock collection owned by the U of Illinois in Lafayette. It was originally labeled as a rock that had been transported by glaciers during the last ice age and had been scoured by passing ice. It was subsequently identified for what it is, and was broken in half for analysis.

Perhaps a quicker test would be you simply try first with a magnet. A hematite (and generally - not always though- a meteorwrong) is not attracted. As your pictures show stones that resemble ordinary chondrites (quasi always attracted), the magnet test will give you a rapid idea/guess. If you want to make sure the wrong is hematite (and not any other type of terrestrial stone), make a simple mark (streak) on a piece of rough china (porcelain). Hematite will give a red-brown mark (hence the name of the mineral). Most stones yield no mark or often some gray-black one.

[meteorite-list] Re: meteorwrong = hematite ?
Hi again, Yes I will probably try to slice it but I still wonder how :) I was planning to just break it but if there's a doubt I'd prefer not :) It's true that I forgot to say that it is clearly attracted to magnet and as the micro picture shows there are (top of the picture) some brigh metalic grains visible (in the holes zone mainly but not only). I haven't tryed to calculate the density yet. Is an hematite never attracted by a magnet ? Cheers from Stuttgart...

RE: [meteorite-list] RE: NWA 869
Dear Christian, I thoroughly enjoyed looking at your endcut and your slice - wonderful! Thanks Bernd! I also appreciate the variety of inclusions. You never know what you're going to get when you cut an 869. I have one that is already sliced but needs work. Perhaps someone could shed some light on the grey inclusions in mine. It is not clear from my pictures but there are four other smaller grey inclusions like the largest one that is 19 mm x 9 mm. It also has a stone in stone. I apologize for its appearance - I generally don't display my sometimes screamingly obvious sawmarks :) This one and the rest of the slices are gonna be even more beautiful (someday).

Re: [meteorite-list] Re: meteorwrong = hematite ?
Xavier, Hematite is NOT attracted by a magnet. And it very often shows a smooth dark red-brown to quasi black surface, often rounded when it is not in (black shiny) crystals . Rarely is the rounded surface rough. If metallic grains are visible, just follow Bernd's suggestion and make a window. If the window (best = polished) shows metallic patches throughout, the next attempt should be the classical test for nickel (dimethylglyoxime test, see e.g. Northon's book or various other general threatises) Good luck!

[meteorite-list] lafayette meteorite
In a book called Meteorites: a photographic study of surface features, part 2 orientation By H.H. Nininger, publication No. 19 1981 printed at ASU pages 44-45 there are 3 images of the stone before it was known to be Martian. Though the images are in black and white they are of the entire stone and the flight markings are incredible. Included are top view, side view, and basal view. The description says the flight lines were mistaken for glacial scracthes for a dozen years in the geology dept. of a large university. The basal view shows the oven effect of bubbled fusion crust. I regard it as nearly a sin to have molested such a beauty, but oh well! The weight of the stone is listed as 600 grams, however every other mention of the TKW I've ever read lists it at 800 grams, can anyone explain this? I wish I knew where a web link to these images existed. Maybe one of the list members would be nice enough to post a link. Truly one of the nicest oriented stones ever.- E.R.
