Writeup from MB 104:
Northwest Africa 10211 (NWA 10211) (Northwest Africa) Purchased: 2014 Classification: Ordinary chondrite (L(LL)3) History: Two fragments totaling 278.7 g were purchased by Sergey Vasiliev in 2014 by internet from a dealer from Morocco. Petrography: The sample has a well-defined chondritic texture. Geochemistry: Analyses of olivine and pyroxene clearly show the highly unequilibrated character of the rock (petrologic type 3). Olivine, Fa15.0±10.4 (Fa0.4-42.7; n=32); low-Ca pyroxene, Fs9.3±6.6Wo0.8±0.9 (Fs1.5-20.2Wo0.1-4.0, n=25). Classification: Based on the chemical data a H, L, or LL classification is impossible. However, based on the chondrule size (generally > 0.4 mm) the rock must be L3 or LL3. In comparison to the LL3 chondrite Krymka, the chondrules in this new chondrite are slightly smaller. Therefore, an L3 chondrite classification is suggested. The olivines show planar fractures clearly indicating shock stage S3. A shock vein has also been observed. The sample is a heavily weathered (W3-4), only having relict metal. | ||||||||||||||||||||||||||||||
