Grove Mountains 090018 (GRV 090018)        72°46’45.3"S, 75°19’23.5"E

Antarctica

Find: 8 Jan 2010

Classification: Iron meteorite (ungrouped)

History: During 2009/2010 field season, 1618 meteorite samples have been collected by CHINARE in Grove Mountains, East Antarctica.

Physical characteristics: This iron meteorite has black fusion crust with total mass 1.46 g. The sample is a piece of iron without silicate inclusions.

Petrography: In polished section, under reflected light, metal and troilite can be seen clearly. There are some dark areas filled with small minerals. Cracks can be seen in these gray minerals.

Geochemistry: The concentrations of trace elements (by ICP-MS) show the iron is ungrouped. The Ni = 8.75%; Co = 0.34%; Ga = 12.2 ppm; Ge = 2.41 ppm; Ir = 3.26 ppm; Au = 0.92 ppm. The Ni-Ga, Ni-Ge, and Ni-Ir diagrams don’t plot in any area of any chemical group.

Classification: Ungrouped iron meteorite

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