Grove Mountains 021536                             72°57'53''S, 75°12'59''E

Grove Mountains, Antarctica

Find: 14 January 2003

Carbonaceous chondrite (CM2)

History and Physical characteristics: J. Li recovered this stone on blue ice in Grove Mountains, Antarctica. It weighs 1.45 g and has an irregular shape. Part of black fusion crust remains.

Petrography: (A. Zhang, PMO; H. Wang, NU) The meteorite contains chondrules, mineral fragments, CAIs, and fine-grained matrix (~70 vol%). Most chondrules are small (200- 300 µm in diameter) and a few are up to 2 mm. Type I PO chondrules are dominant, and type I PP and type II PO chondrules are less abundant. Mineral fragments are mainly olivine and pyroxene. There are a few Ca-Al-rich inclusions containing spinel and Al-rich diopside. Metallic Fe-Ni and sulfides are rare. Some olivine fragments show chemical zoning.

Mineral compositions and Geochemistry: (A. Zhang, PMO; H. Wang, NU) Minerals in chondrules are olivine (Fa0.5-43.5, average = Fa6.7±11.2), and low-Ca pyroxene (Fs1.0-6.0, average = Fs3.04 ± 2.7; Wo0.8-7.9, average = Wo1.77±1.8).

Classification: Carbonaceous chondrite (CM2).

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