Grove Mountains 022888 (GRV 022888) 72° 46' 29"S, 75° 18' 44"E Antarctica Found: 22 January 2003 Classification: Ureilite History: The meteorite was found in No. 4 moraine in Grove Mountains by J. Li. It is 9×9×9 mm in size and partly covered by black fusion crust. The meteorite weighs 0.64 g. Petrography: (S. Li, S. Wang, S. Liu and T.Hong, IGCAS). The meteorite has a cataclastic porphyritic texture, consisting of coarse-grained olivine (21 vol%) and pigeonite (1.4 vol%) embedded in fine-grained carbonaceous matrix (77.6 vol%). The olivine grains have embayed boundaries, and show significantly reduced features with FeO-poor rims (Fa as low as 4.5 mol%). The reduced rims contain abundant tiny inclusions of Ni-poor metal and sulfides. Graphite was identified in the matrix. Almost all olivine grains are characterized with planar and irregular fractures. Geochemistry: (S. Li, S. Wang, S. Liu and T.Hong, IGCAS). Olivine (cores = Fa14.3-23; rims = Fa4.5-11.5), pigeonite (Fs6-15.6Wo5.2-13.6). Classification: Achondrite (Ureilite), moderately shocked, minor weathering. Specimens: All of the sample mass and a polished thin section are on deposit at PRIC. | ||||||||||||||||||
