Grove Mountains 090327 (GRV 090327) 72°49’31.1"S, 75°21’19.6"E Antarctica Find: 15 Jan 2010 Classification: Iron meteorite (IAB-ungrouped) History: During the 2009/2010 field season, 1618 meteorite samples have been collected by CHINARE in Grove Mountains, East Antarctica. Physical characteristics: This iron meteorite is covered with dark brown to black fusion crust, with total mass 43.63 g. The sample is a piece of iron with almost half troilite inclusions, apparent to the naked eye. Dimensions:3.3 × 1.5 × 2.5 mm Petrography: In polished section, there are many veined fissures spread in the metal matrix. Gray minerals fill the veined fissures. A Widmanstaetten pattern is present. Geochemistry: The concentration of trace elements show the iron meteorite belongs to the IAB meteorites: Co = 0.57%; Ni = 10.9%; Ga = 27.5 ppm; As = 13.4 ppm; Ge = 39.3 ppm; Ir = 0.11 ppm; Au = 1.2 ppm. The Ni-Ga, Ni-Ge, and Ni-Ir diagrams indicate that the iron is a member of the IAB chemical group. Classification: Iron meteorite, IAB-ungrouped Specimens: The main mass and one polished section are on deposited at PRIC. | ||||||||||||||||||||||||||
