Sample No.: LEW 87119 Location: Lewis Cliff Weight(g): 12.0 Field No.: 4215 Dimensions (cm): 2x2x2 Meteorite Type: E6 chondrite
Macroscopic Description: Carol Schwarz This specimen is very weathered and fractured with only about 50% fusion crust remaining. The interior is dark brown.
Thin Section (,2) Description; Brian Mason Chondrules are rare and barely discernable in the granular matrix, which consists largely of enstatite (prismatic grains up to 0.2 mm long), with minor amounts of nickel-iron and sulfides, and a little plagioclase. Weathering is extensive, with brown limonitic staining throughout the section. Microprobe analyses show the enstatite is almost pure MgSiO3 (FeO 0.1-0.6%, Al2O3 0.1%, CaO 0.6%); plagioclase composition is An12; the nickel- iron contains 1.6% Si. The meteorite is an E6 chondrite. | ||||||||||||||||||||||||||||
