Physical characteristics: The meteorite consists of a total of 30 dark, magnetic fragments containing yellowish-green silicate in a dark brown matrix. The fragments have a combined weight of 5816 g. Petrography: (A. Irving and S. Kuehner, UWS) Large olivine grains (up to 8 mm across) with interstitial, porous, banded iron hydroxides enclosing sparse angular grains of terrestrial quartz, and accessory chromite, schreibersite and fresh metal (both kamacite and taenite). Mineral compositions and geochemistry: Olivine (Fa12.2-13.0, FeO/MnO = 41.1-42.5). Oxygen Isotopes: (D. Rumble, CIW) analysis of acid-washed handpicked olivine by laser fluorination gave δ18O = 3.65, δ17O = 1.72, Δ17O = -0.198(all in ‰). Classification: Pallasite (main group). The original metal in this specimen is almost entirely weathered to iron hydroxides. View more great items
