Greshake, MNB). The meteorite shows a fine-grained texture with recrystallized matrix dominating over rare and mostly poorly defined chondrules and mineral fragments. Feldspar is abundant in the matrix and minor phases include Cr-rich magnetite and Ca-pyroxene. Mineral compositions and geochemistry:Olivine (Fa29.9), low-Ca pyroxene (Fs25.5). Oxygen Isotopes (I. A. Franchi and R. C. Greenwood, OU): δ17O = -4.72, δ18O = -0.63, Δ17O = -4.39 (all ‰). Classification: Carbonaceous chondrite (CK5/6); minimal shock, moderate to extensive weathering.
