Writeup from AMN 9(2):
Sample No.: ALH84038 Location: Allan Hills Weight (g): 12.3 Field No.: 2468 Dimensions (cm): 2 x 2.3 x 1.5 Meteorite Type: C4 Chondrite
Macroscopic Description: Carol Schwarz This carbonaceous chondrite fragment has black to reddish fusion crust on all but one surface. The interior is dark gray and fine-grained with no features visible. Some white evaporite deposit was exposed.
Thin Section (,3) Description: Brian Mason The section consists largely of finely granular olivine (grains ranging up to 0.1 mm) with rare chondrules and chondrule fragments, and a little opaque material. Microprobe analyses gave the following compositions: olivine, Fa25-30 (one grain Fa39), mean Fa28; pyroxene and plagioclase may be present in small amounts, but were not found with the probe. The meteorite is classified as a C4 chondrite. It is very similar to ALH82135 and the possibility of pairing should be considered. | ||||||||||||||||||||||||
