Grove Mountains 024237 (GRV 024237)        72° 58' 57"S,  75° 15' 0"E

Antarctica

Found: 1 February 2003

Classification: Ureilite

History: The meteorite was found on Moraine I in Grove Mountains by Y. Ju. It has an irregular shape, with nearly no black fusion crust. The meteorite weighs 1.14 g.

Petrography: (G. Wang and D. Wang, GIGCAS). It has a typical ureilite texture, and contains coarse-grained olivine and pyroxenes with less abundant interstitial carbonaceous material. Reduction of olivine grains occurs along boundaries, producing a layer of forsterite with tiny inclusions of metal. Pyroxenes have no reduction zones. 120° triple junctions are common among olivines.

Geochemistry: (G. Wang and D. Wang, GIGCAS) Olivine (cores = Fa16.6-17.5; rims = Fa7.9-17.1), pigeonite (Fs15.4-17.0Wo8.7-10.6 ).

Classification: Achondrite (Ureilite), heavily weathered.

Specimens: All of the sample mass and a polished thin section are on deposit at PRIC.
