  1. Here it is zoomed in. It's definitely a different shade of green than the usual olivine crystals. Does anyone know another green mineral that can be found in meteorites?
  2. Thanks guys! Here is the other side. Does anyone have enough experience with meteorites to venture a guess what could the tiny bright cyan crystal by the right edge, 1/3 to the top be (you have to zoom in - it's tiny)? I haven't seen that kind of color either in this meteorite or the other ones I have.
  3. Do tell me if I am spamming the forum with my meteorite photos. Here is a tiny silce (0.8g, about 2cm long) of the Aba Panu L3 chondrite. Currently, it's my meteorite with the best preserved chondrules, even if it's S4 shock grade. It's also my highest detail photo, both focus stacked and panorama composited, with a macro tubes, reversing ring and a Canon 50mm f/1.8 lens (sharp from edge to edge).
  4. Second one is correct! The first one has even less iron and some of the chondrules are still visible The last one is not correct, though I understand why you would guess as you did. It's some kind of cumulate rock.
  5. Here are a few more, if anyone is still interested in playing... 1. 2. 3.
  6. It is Tagish Lake! It has that characteristic coal look - porous with a few chondrules. Per gram it is currently my most expensive meteorite ($1500/g). I am afraid to take it out of the plastic box it came in. That is why the photo is so low quality - took it through two layers of plastic.
  7. Well done! From what I have seen, it's a typical shergottite though this is a significantly higher magnification than most of the other visible light photos. It's from a NWA 6963, actually pictured on wikipedia as a shergottite example. Maybe I could add my photo Here is another possibly simple one to guess. It's a tiny, 25mg fragment.
  8. Is that a guess or are you getting angry that you can't guess correctly?
  9. Not a diogenite. Here is the other side if it helps. I am not an expert but this small (70mg) fragment is very typical, comparing it with other photos of this kind of meteorite.
  10. Granite, with raw metal flakes? I thought that there was basically no unoxidized iron in earth rocks. This stone was bought from the same dear (Dean Bessy).
  11. Ok, thanks. And the other one I posted? Here is a more magnified view of that I believe are chondrules:
  12. If I haven't bought it from a very reputable and experienced NWA dealer I would also dismissit it right away. I've seen highly weathered meteores that have thin dark weathering fractures but rarely this oriented. The stone is magnetic though. I have windowed another stone and this one also shows thin, dark, mostly paralel lines, though it also has a lot of metal flakes and possible hints of chondrules. To me it looks very similar to weathered H5 slices. The stone is about 1in wide. The first photo is while wet.
  13. Hi! I've recently bought a few bunches of small unclassified NWA meteorites from what I believe is a reputable NWA dealer. They seem to be extremely weathered (can't recognize any fusion crust) and all but a few are magnetic. I have filed and polished a window in three of them and non of them have easily recognizable chondrules (though one has a possible slight hint of them) and only one has possible tiny (0.1mm) metal specks. The sanding dust was medium brown and had a somewhat unpleasant smell (sulfuric?) I am definitely not an expert but this one seems to have sedimentary layers which
