Sample No.:

GRO95645

Location:

Grosvenor Mountains

Dimensions (cm):

1.0x1.0x1.5

Weight (g):

2.42

Meteorite Type:

C2 Chondrite


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.
