Writeup from MB 102:

Los Vientos 055 (LoV 055)        ~24°41’S, ~69°46’W

Antofagasta, Chile

Found: 2012 Jul 14

Classification: Carbonaceous chondrite (CO3)

History: The meteorite was found in 2012 by Luc Labenne in the Atacama Desert.

Physical characteristics: A single stone with about 30% of the surface covered by fusion crust.

Petrography: (J. Gattacceca, CEREGE) Abundant chondrules, predominantly of type I, in a dark matrix. chondrule:matrix ratio is 1:1. Olivine in type I chondrules are zoned. Chondrule size ranges from <100 μm to 700 μm with an average 135±87 μm (N=60).

Geochemistry: Olivine in the range Fa0.6-Fa57.7 (mean Fa16.0±16.4, PMD=86%, N=20). Low-Ca pyroxene Fs1.6Wo0.9. Cr2O3 in ferroan olivine is 0.07±0.11 wt% (N=17). Magnetic susceptibility log χ = 3.95 (χ in 10-9 m3/kg).

Classification: Carbonaceous chondrite (CO3). Moderate weathering

Specimens: 8.9 g and a polished section at CEREGE. Main mass with Labenne.
