Item History & Price

Information:
Reference Number: Avaluer:838497Featured Refinements: Meteorite Slice
Original Description:

On Offer: UNGROUPED CHONDRITE METEORITE PARTIAL SLICE 1.27g
Official name: NWA 12273
Description: A beautiful 1.27 gram partial slice of the ungrouped chondrite NWA 12273. Polished on one side, and rough wire cut finish on reverse. This meteorite defies any known classification, hence the "ungrouped, or "-ung" designation. All that the researchers can say about how this meteorite fits into the current meteoritic taxonomy, is that it is a chondrite. Which is muc...h like asking an ornithologist what type of bird you had discovered and having them come back after extensive analysis and saying its official taxonomy was, "Bird Ungrouped". With visual characteristics similar to a Bencubbinite but with Oxygen isotopic overlap with the LL chondrites, this is a very strange and scientifically significant meteorite. This meteorite is a bit of a cosmic irony seeing as it is extremely metal rich and the LL chondrites are so named for being relatively metal poor. This meteorite pairs with the Chondrite-ung NWA 12379.   What you get: 1.27 gram Ungrouped Chondrite Meteorite Specimen as Shown, Membrane Storage/Display Box, signed 5x7 double sided color Certificate of Authenticity
