Grove Mountains 090312 (GRV 090312)        72°56’4.2"S, 75°19’1.3"E

Antarctica

Found: 2010 Jan 14

Classification: Ureilite

History: One of 1618 meteorite samples collected by CHINARE in the Grove Mountains, East Antarctica, during the 2009-2010 field season.

Physical characteristics (B. Miao, H. Chen, Z. Xia, L. Xie, J. Yao, GUT): A 13.3 g stone has a roundish shape, 3.1x2.2x2.0 cm in size. Its part surface is covered by black fusion crust.

Petrography (B. Miao, H. Chen, Z. Xia, L. Xie, J. Yao, GUT): It consists of coarse-grained olivine, pigeonite and carbon polymorphs. And it shows a typical ureilitic texture, including triple junctions among olivine and pigeonite, microns diamond grains, and reduced zonation of olivine.

Geochemistry (B. Miao, H. Chen, Z. Xia, L. Xie, J. Yao, GUT): Olivine, Fa22.0±0.4 (n = 12), Cr2O3 0.56 - 1.66 wt%, CaO 0.18 - 0.25 wt%; pigeonite, Fs19.7±0.4Wo4.3±1.1 (n = 13), Cr2O3 1.14 - 2.41 wt%.

Classification: Ureilite (monomict)

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