For Sale IconNWA 8667 LL3.15 Chondrite Meteorites for Sale

Location: Northwest Africa, exact location unknown.

Found: Purchased 2009.

Classification: LL3.15 Unequilibrated Chondrite, (S2, W1) Reported by classifier

Description: Physical: A single 559g crusted specimen. Petrography: (A. Irving and S. Kuehner, UWS) Well-formed, fairly closely-packed chondrules (2.1 ± 1.1 mm) occur in a finer grained, metal-bearing matrix. Geochemistry: Olivine (Fa0.4-92.1; Cr2O3 in ferroan olivine 0.11-0.61 wt.%, mean 0.23 wt.%, sd 0.12 wt.%, N = 16), orthopyroxene (Fs0.5-19.1Wo4.3-5.5, N = 3), subcalcic augite (Fs19.3Wo25.1), augite (Fs7.4Wo38.7). Classification: Ordinary chondrite (LL3). The large mean chondrule size is typical of LL chondrites. The very wide range in Fa content of olivine, along with the mean value and standard deviation for Cr2O3 content of ferroan olivines, indicate that this unequilibrated specimen is of a subtype <3.2. (according to the criteria of Grossman and Brearley, 2005).

Comment: I purchased this meteorite in 2009 as a purported pair to NWA 5697. On examining it, I believed that the weathering and chondrule size set this apart from that meteorite. Accordingly, I submitted this to Dr. Tony Irving for analysis on its own account. (Clearly, this piece was not accounted for in the recorded mass of NWA 5697.) The results above reflect that analysis. This was submitted to the Nomenclature Committee of the Meteoritical Society in November of 2014, but no approval or publication in the Meteoritical Bulletin has been forthcomming. I believe that this is potentially an important unequilbrated chondrite and deserves more study. For that reason I am offering these pieces here.
