Sample No.: ALHA80126

Location: Allan Hills

Field No.: 1015

Weight (gms): 34.5

Meteorite Type: H6 Chondrite

 

Physical Description: Roberta Score

Brownish black fusion crust covers all but one surface. The fracture surface has been moderately weathered. Chipping exposed a medium gray interior containing clasts. One particular clast is white and 1 x 1 cm in diameter. Other large clasts are also visible. Oxidation is scattered throughout but mainly as a discontinuous rind. Dimensions: 4.5 x 2 x 2 cm

 

Petrographic Description: Brian Mason

Over most of the section chondritic structure is barely discernable, but one area shows well developed chondrules ranging up to 0.9 mm in diameter. The meteorite consists of olivine and pyroxene with minor amounts of nickel-iron, plagioclase, and troilite. Fusion crust bounds part of the section. Brown limonitic staining is present around metal grains. Microprobe analyses gave the following compositions: olivine, Fa19; pyroxene, Fs17; plagioclase, An12. The meteorite is classified as an H6 chondrite.
