Name: Grosvenor Mountains 95645 This is an OFFICIAL meteorite name. Abbreviation: GRO 95645 Observed fall: No Year found: 1995 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 2.42 g
Macroscopic Description: Kathleen McBride This carbonaceous chondrite has gray-black, fractured fusion crust. The fusion crust has a slight greenish cast under fluorescent lighting. Some areas are weathered and rusty. The interior reveals a black, fine-grained matrix with very little rust, but weathered evaporites.
Thin Section (,2) Description: Brian Mason The section shows a close-packed aggregate of small chondrules (up to 0.2 mm across), chondrule fragments, and mineral grains with interstitial black matrix. The chondrules and mineral grains are made up of a fine-grained weakly birefringent material; microprobe analyses indicate that this material is probably an iron-rich serpentine. The meteorite is tentatively identified as a C2 chondrite.
