Los Vientos 315 (LoV 315)        24°40’17.0’’S, 069°55’49.6’’W

Antofagasta, Chile

Find: 2017 Feb

Classification: Ordinary chondrite (H3)

History: Found on granodiorite pediment surface while meteorite prospecting with six-person team.

Petrography: (J. Gattacceca, CEREGE) Packed well-delineated chondrules (average apparent diameter 430±210 µm, n=36). Opaque are metal and sulfides, present as composite blebs up to 200 µm in the matrix.

Geochemistry: Olivine Fa18.4±6.4, Fa PMD 29%, Cr2O3 0.22±0.15 wt% (n=16). Low-Ca pyroxene Fs13.0±2.3Wo0.4±0.1 (n=4). Ca-pyroxene Fs20.9Wo23.0 (n=1).

Classification: Ordinary chondrite (H3). H group from chondrule size. Cr2O3 content of olivine suggest a low petrographic sub-type 3.15 (Grossman and Brearley, 2005).
