This text was reprinted from AMN 1(3) in AMN 4(1). In some cases, it may be an updated version from the original. Sample No.: ALHA77282 Location: Allan Hills Field No.: Y78O10306 Weight (gms): 4127.1 Meteorite Type: L6 Chondrite
Physical Description: Specimen is angular. Approximately 70% of the meteorite's surface is covered with fusion crust, which is ~2 mm thick. The fractured surface is weathered. This surface has a granular texture and contains rounded to angular, light colored clasts. The fresh surface revealed during chipping is whitish to whitish-gray and contains tiny flecks of metal. This is not a complete specimen. Approximate dimensions are: 17.5x13.0x9.0 cm.
Petrographic Description: Brian Mason This meteorite resembles ALHA77286 and 77281 in all respects, except possibly for a lesser degree of weathering, limonitic staining being limited to areas around nickel-iron grains; however, this may simply reflect a source further from the surface. | ||||||||||||||||||||
