Los Vientos 266 (LoV 266) 24°39.972’S, 69°55.608’W Antofagasta, Chile Find: 2017 Feb 20 Classification: Ordinary chondrite (H3.15) History: Found by driving in a plain while meteorite prospecting with a six-person team. Petrography: Olivine Fa17.2±10.0, Fa PMD=49%, range Fa1.8-38.7 (n=17). Cr2O3 in ferroan olivine 0.24±0.14 (n=16). Orthopyroxene Fs12.3±7.4Wo0.8±0.5 (n=11). Based on the structural order of the polyaromatic matter assessed by Raman spectroscopy (Lydie Bonal, IPAG), this meteorite appears as metamorphosed as Bishunpur (type 3.15). The Raman spectroscopy parameters of interest are FWHM-D (cm-1)=175.2±11.7, ID/IG=1.00±0.02, N=7 (see Bonal et al. 2016, figure 6). Geochemistry: Chondrite with well-delineated chondrules (average apparent diameter 400±260, n=26) set in a fine-grained matrix (19 vol% by point counting, n=149). Opaques are FeNi metal and sulfides. Metal is present as blebs in the matrix up to 600 μm. Classification: Ordinary chondrite (H3.15). Ordinary chondrite based on mineralogy, matrix abundance. H based on magnetic susceptibility (interpreted in the light of the weathering grade W2) and chondrule size. Subtype 3.15 based on Raman spectroscopy and the Cr2O3 content of ferroan olivine. Specimens: Type specimen at CEREGE. Main mass with Sergey Vasiliev. | ||||||||||||||||||||||||||||||||||||||
