Writeup from MB 102:

Catalina 079 ~25°14’S, ~69°43’W

Antofagasta, Chile

Found: 2010 Feb 9

Classification: Mesosiderite (group B)

History: The meteorite was found by R. Martinez in the Atacama desert among ordinary chondrite fragments. It was later identified as a different meteorite through magnetic susceptibility screening.

Physical characteristics: A single rusted stone of 4.4 g

Petrography: (J. Gattacceca, CEREGE) Silicates are mainly orthopyroxene with lesser plagioclase and Ca-pyroxene. Abundant metal in elongated grains up to 5 mm. Chromite, silica, troilite, merrillite are present. Modal abundances: pyroxene 49%, plagioclase 15%, FeNi metal 23%, metal weathering products 13%, troilite 1%, silica 1%.

Geochemistry: Orthopyroxene Fs_34.4±0.0Wo_3.3±0.1, FeO/MnO=24.0. Ca-pyroxene Fs_18.0±2.0Wo_36.8±5.2, FeO/MnO=21.1. Plagioclase An_89.8Ab_10.0Or_0.2.Chromite Cr/(Cr+Al)=0.81. Magnetic susceptibility log χ = 5.56 (X in 10-9 m3/kg).

Classification: Mesosiderite (type B). Moderate weathering.

Specimens: 2 g and a polished section at CEREGE. 2 g at MMC.
