Sample No.: ALHA80101

Location: Allan Hills

Field No.: 1023

Weight (gms): 8725.0

Meteorite Type: L6 Chondrite

Physical Description: Carol Schwarz

he sample has black fusion crust on two surfaces. The texture of the rest of the meteorite is rough and has weathered to a reddish-brown color. Some distinct chondrules or clasts that are cream colored can be distinguished. The sample shows linear fractures which are more severely weathered. The interior of this stone is gray with numerous oxidation halos. A darker gray weathering rind is discontinuous. Where broken along fractures, some white evaporate deposit was exposed. This specimen is similar to ALHA80103 and ALHA80105. The samples have weathered too much to fit together as one sample. Dimensions: 31 x 17 x 15 cm.

Petrographic Description: Brian Mason

Chondrules are sparse and poorly defined, tending to merge with the granular groundmass, which consists largely of olivine and pyroxene, with minor amounts of plagioclase, troilite, and nickel-iron. A moderate amount of limonitic staining is present around .he nickel-iron grains. Microprobe analyses gave the following mineral compositions: olivine, Fa24; orthopyroxene, Fs20; plagioclase, An11. The meteorite is classified as an L6 chondrite. Polished thin sections of ALHA80103, 80105 are identical in texture, mineral compositions, and degree of weathering with ALHA80101, indicating that these three specimens are pieces of a single meteorite.
