Catalina 002        25°14’S, 69°43’W

Antofagasta, Chile

Found: 2010 Oct 01

Classification: Ordinary chondrite (LL3)

History: The meteorite was found by E. Christensen in the Atacama desert, Chile.

Physical characteristics: A single brownish stone, 70% of the surface covered by fusion crust.

Petrography: (J. Gattacceca, CEREGE) Cut surfaces reveal closely packed chondrules of various textural types. The meteorite is brecciated with darker clasts (up to cm) set in a lighter host lithology. Mean Chondrule diameter is 820 μm (n=39). Dusty olivines are present in the darker clasts.

Geochemistry: Host lithology: olivine Fa_19.5 (Fa_0.5-30.1, PMD = 41%, n = 28); orthopyroxene Fs_20.7 (Fs_7.6-30.1, PMD = 27%, n = 8) Wo_1.6±0.8; Cr₂O₃ in ferroan olivine is 0.15±0.12 wt.% with a maximum 0.52 wt.% (n = 27). Dark clasts: olivine Fa_15.0 (Fa_0.6-29.2, PMD = 67%, n = 13); orthopyroxene Fs_12.7 (Fs_2.9-25.8, PMD = 43%, n = 7) Wo_1.2±1.0; Cr₂O₃ in ferroan olivine is 0.11±0.22 wt.% with a maximum 0.73 wt.% (n = 10). Magnetic susceptibility log χ = 3.60.

Classification: Ordinary chondrite breccia (LL3). Estimated sub-types are LL3.3 for the host lithology, LL3.2 for the clasts (all ±0.1). Weathering grade W4.

Specimens: 14 g, a polisehd section, and a thin section at CEREGE.
