Grove Mountains 090333 (GRV 090333)        72°49’31.1"S, 75°21’19.6"E

Antarctica

Find: 15 Jan 2010

Classification: Iron meteorite (IAB-sLM)

History: During 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 gray to black fusion crust, with total mass 38.02 g. The whole iron meteorite is nearly an ovoid. Some brown to dark-red traces appear in the cut face. Silicate inclusions cannot be observed by naked eye. Dimensions:2.8 × 1.2 × 2.1 mm.

Petrography: In polished section, there are some dark, long bars of kamacite that are mixed with taenite and cracked minerals. Some small, dark minerals also can be seen in the matrix. A Widmanstaetten patter is visible.

Geochemistry: The concentrations of trace elements show the iron meteorite belongs to the IAB chemical group: Co = 0.51%; Ni = 13.45%; Ga = 33.7 ppm; As = 17.7 ppm; Ge = 78.4 ppm; Ir = 0.83 ppm.

Classification: IAB iron meteorite

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