Grove Mountains 023158 (GRV 023158)        72° 46' 26"S,  75° 20' 21"E

Antarctica

Found: 22 January 2003

Classification: Carbonaceous chondrite (CV3)

History: B. Miao recovered this stone on a moraine in Grove Mountains, Antarctica. It weighs 1.18 g and has an irregular shape. Part of a black fusion crust remains.

Petrography: (S. Song, NU) The meteorite contains ~43 vol% chondrules, ~54 vol% fine-grained matrix, and ~3 vol% refractory inclusions. Some chondrules are large (up to ~2 mm). Porphyritic olivine chondrules are dominant. Some olivine fragments show chemical zoning. Most FeNi-metal grains were severely weathered.

Geochemistry: (S. Song, NU) Olivine (Fa1.2-55.3, average= Fa27.3±19.9), and low-Ca pyroxene (Fs1.0-2.8, average=Fs1.8±0.9; Wo0.8-1.4, average=Wo1.1±0.3).

Classification: Carbonaceous chondrite (CV3)

Specimens: PRIC holds the main mass and a polished section.
