Writeup from AMN 10(2):
Sample No.: EET83334 Location: Elephant Moraine Weight (g): 2.5 Field No.: 2706 Dimensions (cm): 1.5 x 1.5 x 1 Meteorite Type: C2 Chondrite
Macroscopic Description: Roberta Score A small amount of fusion crust remains on this otherwise black, massive stone.
Thin Section (,4) Description: Brian Mason The section shows a few chondrules (up to 0.9 mm across) and numerous small mineral grains in an opaque matrix. The chondrules and mineral grains consist almost entirely of pale green weakly birefringent serpentinous material. Trace amounts of nickel-iron are present as minute grains. Microprobe analyses show serpentine of variable composition, averaging SiO2 39.6, Al2O3 3.3, FeO 15.3, MgO 27.9%; some small grains of calcite and dolomite were found. The meteorite is a C2 carbonaceous chondrite; the pervasive serpentinization appears to distinguish it from other Elephant Moraine C2 chondrites. | ||||||||||||||||||||||||||||
