Sample No.: ALHA80130

Location: Allan Hills

Field No.: 1014

Weight (gms): 5.3

Meteorite Type: H6 Chondrite

 

Physical Description: Roberta Score

The exterior of this stone is highly weathered with only two small patches of fusion crust remaining. The interior is nearly completely weathered except for a small (2 x 2 mm) area of medium gray material. Dimensions: 2 x 1.5 x 1 cm

 

Petrographic Description: Brian Mason

Chondrules are sparse and poorly developed, their borders merging with the granular groundmass, which consists largely of olivine and pyroxene, with minor amounts of plagioclase, nickel-iron, and troilite. Brown limonitic staining is pervasive throughout the section. Microprobe analyses gave the following compositions: olivine, Fa18; pyroxene, Fs16; plagioclase, An12; one grain of accessory merrillite was analyzed. The meteorite is classified as an H6 chondrite.
