Sample No.: ALH85005, 85007, 85008, 85009, 85013

Location: Allan Hills

Field Nos.: 2268; 2209; 2284; 2240; 2257

Weight (g): 18.9; 82.0; 32.1; 46.6; 130.4

Dimensions (cm): 4x2x3; 5x4x4; 3x3x3.5; 4.5x3x3; 6x5x3.5

Meteorite Type: C2 Chondrite

Macroscopic Description: René Martinez

ALH85013 is completely covered with fusion crust; ALH85005 and 85009 retain some weathered fusion crust. The others have no fusion crust and have a knobby appearance with inclusions protruding from the surface. The interiors appear relatively unweathered, black, fine-grained, and contain irregular white inclusions that are <0.5 mm in longest dimension.

Thin Section (ALH85005,4) Description: Brian Mason

The section consists largely of black opaque matrix, through which are scattered small mineral grains (up to 0.2 mm) and sparse chondrules and chondrule fragments. The chondrules and most of the mineral grains consist of olivine, usually close to MgSiO4 in composition but with some more iron-rich. Pyroxene is less common, and is close to MgSiO3 in composition. A few grains of calcite were noted. The meteorite is a C2 chondrite; ALH85007, 85008, 85009, and 85013 are very similar and the possibility of pairing should be considered.
