Writeup from AMN 8(1):
Sample No.: EET83213 Location: Elephant Moraine Weight (g): 2727.0 Field No.: 2875 Dimensions (cm): 16 x 15 x 7 Meteorite Type: L3 Chondrite
Macroscopic Description: Carol Schwarz Dull fractured fusion crust occurs on most of EET83213. Evaporite deposit is present on several surfaces. Interior is greenish-gray with numerous white, cream, and darker gray colored inclusions/chondrules. Metal is present.
Thin Section (,4) Description: Glenn MacPherson Moderate limonitic staining is locally present, suggesting mild to moderate weathering. Chondrules up to 3-mm diameter are very sharply defined, and set in a brown matrix. Isotropic clear brown glass is preserved in some chondrules. Monoclinic pyroxene is very common and was found in the composition range Fs3 to Fs26. The range of olivine compositions found is Fa13 to Fa30. Metal and troilite are subequal in amount. At least two metal phases are present in plessitic intergrowths, and tetrataenite may also be present. This meteorite is probably an L3 chondrite. | ||||||||||||||||||||||||
