Grove Mountains 051993 (GRV 051993)        72°46’50"S, 75°18’23.7"E

Antarctica

Find: 16 Jan 2006

Classification: Ordinary chondrite (H3)

History: During 2005/2006 field season, 5354 meteorite samples have been selected by CHINARE in Grove Mountains, East Antarctica.

Physical characteristics: This meteorite weighs 7.95 g, the edges and corners are obvious. It has a fusion crust shell and is dark brown in color.

Petrography: Chondrules are very sharply defined, suggesting a type-3 classification. Chondrule types include,porphyritic chondrules, and barred olivine chondrule. Olivine grains exhibit sharp optical extinction, indicative of shock stage S1. SEM observations show that the metal/sulfide are up to 30 vol%, indicate this meteorite belongs to H group.

Geochemistry: Olivine Fa19.57±4.65, range Fa7.60-28.53. Pyroxene Fs16.53±5.70, range Fs3.9-30.16.

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