NWA 12416 C3 - Ung 0. 21g RARE Carbonaceous Chondrite
Item History & Price
| Reference Number: Avaluer:15751965 |
Item for auction is a 0.21g fragment of NWA 12416 C3 ungrouped carbonaceous chondrite meteorite. The first batch of this material was purchased by Adam Aaronson in July 2018 in Temara, Morocco; this material was purchased from the same Moroccan source by Mark Lyon. The material consists of numerous small black, friable stones, some completely fusion crusted (total weight 875 g). Petrography consists of granular chondrules (apparent diameter 350±210 µm, N = 15) together with sparse mi...neral fragments and AOA (but no identifiable CAI or related mineral grains) are set in very fine grained matrix (~50 vol.%, black in thin section) containing minor kamacite and pentlandite. No phyllosilicates were detectable by X-ray diffraction. NWA 12416 is a Carbonaceous chondrite (ungrouped Type 3). Oxygen isotope compositions plot at more negative Δ17O values than for CV, CK and most CM chondrites, and the absence of phyllosilicates excludes affinity to typical CM2 chondrites. This anomalous meteorite would complement any collection. It comes in a quality labeled display case for protection and years of viewing pleasure, along with a Big Kahuna Meteorites Certificate of Authenticity. Scale cube in photo is 1cm on each side, and not included in sale. Big Kahuna combines shipping, and addresses must be in the English language, to facilitate customs input at US Postal Service.
