Writeup from AMN 4(1):

Sample No.: ALHA79005

Location: Allan Hills

Field No.: 1195

Weight (gms): 60.0

Meteorite Type: H6 Chondrite


Physical Description: Roberta Score

When this stone was received in the laboratory, the sample was broken in three pieces that fit together perfectly. Dull black fusion crust totally covers this meteorite. The interior has a 2 mm thick weathering rind around the entire inside. Crystal faces of the grains are visible. Dimensions: 3.5 x 5 x 1.5 cm.


Petrographic Description: Brian Mason

The section shows sparse and poorly defined chondrules tending to merge with the granular groundmass, which consists largely of olivine and pyroxene, with minor amounts of nickel-iron, plagioclase, and troilite. Some limonitic staining is present on the edge of the section, probably the result of near-surface weathering. Microprobe analyses show olivine (Fa18), pyroxene (Fs16), and plagioclase (An11) of uniform composition. The meteorite is classified as an H6 chondrite.
