Writeup from AMN 9(3):
Sample No.: EET84302 Location: Elephant Moraine Weight (g): 59.6 Field No.: 2195 Dimensions (cm): 4 x 3 x 2.5 cm Meteorite Type: Achondrite
Macroscopic Description,: Roberta Score The exterior of this stone is mostly covered with thin fusion crust. Medium-grained pyroxene, plagioclase and some scattered metal comprise the heavily oxidized interior of EET84302.
Thin Section (,3) Description: Brian Mason The section shows an anhedral granular aggregate (grain size 0.1-0.4 mm), consisting largely of olivine and orthopyroxene, with minor amounts of plagioclase, diopside, nickel-iron, and troilite. Weathering is extensive, with limonitic staining throughout the section. Microprobe analyses gave the following compositions: olivine, Fa5; orthopyroxene, Wo2Fs8; diopside, Wo42Fs3; plagioclase, An23. Texturally this meteorite is an achondrite. However, it resembles a silicate inclusion from an iron meteorite; inclusions with similar texture and mineral compositions have been described from several iron meteorites. | ||||||||||||||||||||||||||||
