Writeup from AMN 4(1):
Sample No.: ALHA79006 Location: Allan Hills Field No.: 1197 Weight (gms): 40.9 Meteorite Type: H5 Chondrite
Physical Description: Roberta Score Dull black fusion crust covers all but two surfaces of this meteorite. Areas devoid of fusion crust are reddish-brown in color and contain clasts. The interior material is brownish-yellow in color and contains many clasts. The surface that was exposed was along a pre-existing crack and therefore the stone may be less weathered than it appears at first glance. Dimensions: 6 x 2.5 x 2 cm.
Petrographic Description: Brian Mason The section is moderately chondritic, with chondrules ranging from 0.3-1.2 mm in diameter. The chondrules are set in a fine- to medium-grained groundmass, which consists largely of olivine and pyroxene, with minor amounts of nickel-iron and troilite; brown limonitic staining is present around the nickel-iron grains. Remnants of fusion crust, up to 0.3 mm thick, are present along one edge. Microprobe analyses show olivine (Fa18) and pyroxene (Fs15) of uniform composition. The meteorite is classified as an H5 chondrite. | ||||||||||||||||||||
