Grove Mountains 023159 (GRV 023159) 72° 46' 26"S, 75° 20' 21"E Antarctica Found: 22 January 2003 Classification: Carbonaceous chondrite (CV3) History: The meteorite was found in No. 4 moraine in Grove Mountains by B. Miao. It is 10×10×16 mm in size and partly covered by black fusion crust. The meteorite weighs 1.31 g. Petrography: (S. Li, S. Wang, S. Liu and T.Hong, IGCAS). The chondrules varies from ~70 μm to ~2000 μm in diameter (average ~600 μm; abundance ~39 vol%). Most chondrules are GOPs, a few are POPs. Fine-grained Matrix is mainly composed of fayalitic olivine. The matrix/chondrule ratio is about 1.6. Metallic Fe-Ni and sulfides are accessory minerals and mainly in chondrules. Sparse CAI consisting mainly of spinel, hiboniteand fassaite. Geochemistry: (S. Li, S. Wang, S. Liu and T. Hong, IGCAS). Olivine is highly heterogeneous within and among chondrules, with Fa = 2.1-55.6 mol% (average 22.0, n=20). Low Ca-pyroxene contains low FeO, (Fs1.1-4.7Wo0.1-1.3,), Minor phases are kamacite, sulfides, plagioclase and Ca carbonates. Classification: Carbonaceous chondrite (CV3) Specimens: All of the sample mass and a polished thin section are on deposit at PRIC. | ||||||||||||||||||
