Writeup from MB 106:

Los Vientos 150 (LoV 150)        ~24°41’S, ~69°46’W

Antofagasta, Chile

Find: 2016 March

Classification: Carbonaceous chondrite (CO3)

History: The stone was found lying at the surface in the Atacama desert.

Physical characteristics: A single, angular, brown stone with smooth surface and few remnants of fusion crust. Cut surface reveals a brown interior with small chondrules.

Petrography: Well-defined chondrules (average apparent diameter 190±100 μm, N=34) mostly of type I, and small CAIs set in fine-grained iron-rich matrix. Modal abundances: chondrules+fragments 67 vol%, matrix 33% (point counting, N=138). Abundant metal and sulfides.

Geochemistry: Olivine in the range Fa2.2-23.9 (mean Fa18.1±6.2, PMD=29%, N=16). Cr2O3 in ferroan olivine 0.09±0.07 wt.% (N=16). Low-Ca pyroxene Fs6.4±5.0 Wo2.8±1.7 (N=5). Magnetic susceptibility log χ (× 10-9 m3/kg)=5.01.

Classification: Carbonaceous chondrite (CO3). Estimated subtype >=3.2 based on olivine Fa PMD and Cr2O3 content.

Specimens: 22 g at CEREGE. Main mass with ArtMet collection, Poland.
