Writeup from MB 101:
Catalina 002 25°14’S, 69°43’W
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 Fa19.5 (Fa0.5-30.1, PMD = 41%, n = 28); orthopyroxene Fs20.7 (Fs7.6-30.1, PMD = 27%, n = 8) Wo1.6±0.8; Cr2O3 in ferroan olivine is 0.15±0.12 wt.% with a maximum 0.52 wt.% (n = 27). Dark clasts: olivine Fa15.0 (Fa0.6-29.2, PMD = 67%, n = 13); orthopyroxene Fs12.7 (Fs2.9-25.8, PMD = 43%, n = 7) Wo1.2±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.
