Grove Mountains 020175                             72°58'45''S, 75°15'42''E

Grove Mountains, Antarctica

Find: 7 January 2003

Mesosiderite

History and Physical characteristics: J. Li recovered this stone on blue ice in Grove Mountains, Antarctica. It weighs 1.54 g and has an irregular shape. No fusion crust remains.

Petrography: (L. Wang, A. Zhang, PMO; H. Wang, J. Cao, NU) The stone contains 42.4 vol% metallic Fe-Ni and troilite. The silicate part consists mainly of low-Ca and high-Ca pyroxene (47 vol%), plagioclase (10.1 vol%) and silica (0.5 vol%), with minor olivine. Both low-Ca and high-Ca pyroxene grains show exsolution lamellae. Some low-Ca pyroxene grains exhibit chemical zoning.

Mineral compositions and Geochemistry: (L. Wang, A. Zhang, PMO; H. Wang, J. Cao, NU) Olivine (Fa45.7-46.7, average = Fa46.3±0.6), pyroxene (Fs12.5-57.0, average = Fs34.9±8.4; Wo1.5-43.8, average = Wo8.0±13.5), plagioclase (An85.7-96.6, average = An91.2±2.7; Ab3.4-12.1, average = Ab8.4±2.6).

Classification: Mesosiderite.

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