Writeup from AMN 5(1):

Sample No.: ALHA80111

Location: Allan Hills

Field No.: 1016

Weight (gms): 42.4

Meteorite Type: H5 Chondrite


Physical Description: Carol Schwarz

The specimen is totally covered with smooth thin black fusion crust. The bottom is shiny and iridescent while the remainder is dull with some polygonal fracturing. The interior of the stone is gray with some oxidation halos. Dimensions: 4.5 x 4 x 2.5 cm


Petrographic Description: Brian Mason

Chondritic structure is moderately well developed, but the margins of many of the chondrules are diffuse, tending to merge with the granular ground-mass, which consists largely of olivine and pyroxene, with minor amounts of nickel-iron and troilite. Brown limonitic staining surrounds the nickel-iron grains. Microprobe analyses gave the following compositions: olivine, Fa18; orthopyroxene, Fs16. A little fine-grained plagioclase, An12, was analyzed, and one grain of merrillite. The meteorite is classified as an H5 chondrite.
