Writeup from AMN 4(1):
Sample No.: ALHA77088 Location: Allan Hills Field No.: 77122783 Weight (gms): 51.15 Meteorite Type: H5 Chondrite
Physical Description: Specimen is angular and highly weathered. Several fissures are obvious on the brownish-black surface. Approximately 30% of the surface is slightly rounded and represents the remnants of a fusion crust. From field photographs it is apparent that the S-E surface was in contact with the ice. This is not a complete specimen. A thin section sample was removed from the T surface. The specimen appears to be weathered throughout. The longest dimension is nearly 3.5 cm.
Petrographic Description: Brian Mason This meteorite is similar in texture, mineral composition, and degree of weathering to ALHA77086, which suggests that these two stones may be separate pieces of the same meteorite. | ||||||||||||||||||||||||
