Writeup from MB 103:

Los Vientos 051 (LoV 051) ~24°41’S, ~69°46’W

Antofagasta, Chile

Found: 2010 Sep 30

Classification: Carbonaceous chondrite (C3, ungrouped)

History: A single stone was found in the Atacama desert in September 2010 by E. Christensen and A. Serio.

Physical characteristics: A flat rusted stone with caliche on the bottom side. Cut face shows chondrules, some armored with metal and sulfides, set in a brownish matrix.

Petrography: (J. Gattacceca. CEREGE) Chondrules, mainly of type I, up to 2.5 mm (average diameter 940±280 μm) make up ~50% of the meteorite. Metal blebs up to 1 mm in diameter are found in and around the chondrules and in the matrix.

Geochemistry: Olivine Fa_13.1±1.4, PMD=8%, n=31, FeO/MnO=57.6, Cr₂O₃=0.10± 0.17 wt.%; orthopyroxene Fs_9.2±3.3Wo_1.1±0.6, Fs PMD=32%, n=9, FeO/MnO=38.7. Some chondrules contain plagioclase An_92.9Ab_7.1Or_0.1.Oxygen isotopic composition (J. Gattacceca, C. Sonzogni, CEREGE) is δ¹⁷O = -4.90 ‰, δ¹⁸O = -1.24 ‰, Δ¹⁷O = -4.25‰ (analysis of one acid-washed 1.5 mg bulk sample). Magnetic susceptibility log χ =5.24.

Classification: Carbonaceous chondrite. Texture and chondrule size resemble CR chondrites, however mineral composition and oxygen isotopes indicate C3-ung. Minor weathering.

Specimens: 15 g and a polished section at CEREGE. Main mass with Eric Christensen.
