Writeup from AMN 10(2):
Sample No.: EET83311 Location: Elephant Moraine Weight (g): 15.3 Field No.: 1360 Dimensions (cm): 2.5 x 2.5 x 1.5 Meteorite Type: C4 Chondrite
Macroscopic Description: Roberta Score Frothy fusion crust covers all of EET83311. Interior is medium to dark gray in color and has a massive texture. Glassy, linear striations were exposed when the stone was cleaved.
Thin Section (,2) Description: Brian Mason Chondritic structure is barely discernable, the section consisting largely of finely granular olivine (grains ranging up to 0.2 mm, with a few larger), with a little plagioclase and opaques, largely magnetite (pyroxene is probably present, but was not certainly identified). Microprobe analyses gave the following compositions: olivine, Fa31; plagioclase, An49. The meteorite is similar to Karoonda in texture and mineral compositions, and is tentatively identified as a C4 chondrite. | ||||||||||||||||||||||||
