Los Vientos 250 (LoV 250) 24°41.093’S, 69°50.533’W Antofagasta, Chile Find: 8 Feb 2018 Classification: HED achondrite (Diogenite) Physical characteristics: Single stone partially covered by fusion crust with flow lines. Sawn surface shows a yellowish-orange interior with abundant opaque grains and metal. Petrography: Thin section shows pyroxene (95 vol%) grains up to 6 mm in the long dimension with abundant shock veins. Chromite spinel grains (3 vol%) are well scattered through the sample and measure up to 3 mm and are usually associated to iron oxide. Metal grains (2 vol%) are in the range 1-3 mm. Olivine occurrence is rare. Additional minerals are Si polymorphs, FeS and Ti-spinel. Geochemistry: Low-Ca pyroxene composition in the range Fs23.2-23.5Wo0.9-1.2 (mean Fs23.4±0.2Wo1.0±0.2, N=8), with FeO/MnO=26.0±1.2. Mean olivine composition is Fa35.3±0.2 (N=2). Chromite exhibits Cr/(Cr+Al) values of 0.82±0.05 (N=8). Metal is Ni-free. No plagioclase has been found in the section studied. | ||||||||||||||||||||||||||||||
