Sample No.: ALHA80132 Location: Allan Hills Field No.: 1097 Weight (gms): 152.8 Meteorite Type: H5 Chondrite
Physical Description,: Roberta Score Most of this flat stone is covered with dull brownish-black fusion crust. Flow bands are prominent on one surface. Several fractures penetrate into the interior. A large weathering rind was revealed when the specimen was chipped. The unweathered areas, which are light gray in color, contain inclusions. Dimensions: 8 x 4.5 x 3 cm.
Petrographic Description: Brian Mason Chondritic structure is moderately well developed, but chondrule margins are blurred, tending to merge with the granular groundmass, which consists largely of olivine and pyroxene, with minor amounts of nickel-iron and troilite. Plagioclase was not certainly identified. Limonitic staining is extensive around metal grains, and veinlets of limonite are present near one edge of the section. Microprobe analyses gave the following mineral compositions: olivine, Fa18; orthopyroxene, Fs16. The meteorite is classified as an H5 chondrite. | ||||||||||||||||||||
