Writeup from MB 104:
Catalina 108 ~25°14’S, ~69°43’W Antofagasta, Chile Find: 2014 May 17 Classification: Mesosiderite (group B) History: A single fragment was found by Rodrigo Martinez in May 2014 while he was looking for meteorites. Physical characteristics: Irregular brownish fragment. Petrography: (J. Gattacceca, CEREGE) Coarse crystalline rock rock with recrystallized texture (triple junctions). Main minerals are pyroxene, plagioclase to 500 μm, metal (typical size 250 μm, to 1.2 mm), chromite to 50 μm, silica polymorph to 200 μm. Modal abundances (by point counting, N=491): pyroxene 51%, plagioclase 14%, metal 12%, troilite 5%, oxides (from weathering) 19%. Geochemistry: Pyroxenes: orthopyroxene Fs34.4±0.3 Wo3.1±0.3 (N=3), augite Fs18.9Wo33.4 (N=1), FeO/MnO=26.6 (N=5). Plagioclase An91.6Ab8.1Or0.3, chromite Cr#=81. Magnetic susceptibility log χ =5.45 (χ in 10-9 m3/kg). Classification: Mesosiderite (type B). Likely paired with Catalina 079 that was found 1.6 km away. Moderate weathering. Specimens: 21 g at CEREGE. Main mass at MMC. | ||||||||||||||||||||||||||||||||||||
