Macroscopic Description: Carol Schwarz These carbonaceous chondrite fragments are all fine-grained and black in color. Some of the fragments contain small white inclusions. Salt deposit has formed on most of them.
Thin Section Description: Brian Mason These meteorites are C2 chondrites characterized by almost complete serpentinization and can confidently be paired with ALH84029, 84030, 84031, 84032, 84034, 84042, and 84044 (Antarctic Meteorite Newsletter 8(2)); ALH83100 and 83102 are very similar. The major component is a brown to black phyllosilicate matrix enclosing green to pale brown phyllosilicate pseudomorphs of chondrules, inclusions, and mineral grains. Minute grains of calcite are common. Rare grains of forsteritic olivine and clinoenstatite may be present. | ||||||||||||||||||||||||
