Grove Mountains 051523                             72°56'6.2''S, 75°18'51''E

Grove Mountains, Antarctica

Find: 11 January 2006

Achondrite (eucrite)

History and Physical characteristics: The meteorite was found in a small moraine west to the middle segment of the Gale Escarpment in Grove Mountains by Y. Lin. It has a peanut-like shape most covered by glazy fusion crust. White clasts of plagioclase can be seen under the crust and areas without the crust. The meteorite weighs 0.8 g.

Petrography: (Y. Lin, S. Hu, T. Liu and L. Feng, IGGCAS) It consists mainly of coarse-grained pyroxenes and plagioclase. Pyroxenes show exsolution of augite lamellae in pigeonite or vice-versa. The meteorite is heavily shocked and brecciated. Tiny inclusions of chromite in pyroxene are common. Among large fragments of silicates, there is regolith-like matrix. Sulfides occur mainly along cracks and/or boundaries of pyroxenes.

Mineral compositions and Geochemistry: (Y. Lin, T. Liu, S. Hu, and L. Feng, IGGCAS). Low Ca-pyroxene (Fs54.1-4.1; FeO/MnO = 29.4-0.7) augite (Fs22Wo44), plagioclase (An87.6-90.2Ab9.6-12.0). Olivine (Fa75; FeO/MnO = 38-41).

Classification: Achondrite (eucrite); extensively shocked, monomict breccia, minimally weathered.

Type specimens: PRIC holds the main mass and a polished section.
