Grove Mountains 090994 (GRV 090994)        72°59’5.6"S, 75°14’55.2"E

Antarctica

Found: 2010 Feb 1

Classification: Mesosiderite

History: One of 1618 meteorite samples collected by CHINARE in the Grove Mountains, East Antarctica, during the 2009-2010 field season.

Physical characteristics (B. Miao, H. Chen, Z. Xia, L. Xie, J. Yao, GUT): The 369.1 g stone has an irregular shape. It contains an even distribution of metal and silicates portions. It has no fusion crust.

Petrography (B. Miao, H. Chen, Z. Xia, L. Xie, J. Yao, GUT): It consists of 35 vol% of metallic Fe-Ni and the silicate portion. The silicate part consists of various large fragments of pyroxenes, plagioclase.

Geochemistry (B. Miao, H. Chen, Z. Xia, L. Xie, J. Yao, GUT): Kamacite, Ni 4.71 - 6.22 wt%; Taenite, Ni 36.2 - 46.1 wt%. The metal has no detectable Co. Orthopyroxene, Fs27-33Wo2-5, FeO/MnO (in weight) = 21.

Classification: Mesosiderite, significantly weathered.

Specimens: The main mass and one thin section are on deposited at PRIC.
