PETROGRAPHY, MINERAL CHEMISTRY AND CLASSIFICATION OF SOME GROVE MOUNTAINS METEORITES
摘要
Abstract
The study of 99 meteorites that were collected from the Grove Mountains , Antarctica , indicates that these me-teorites belong to ordinary chondrite groups H , L, and LL, Ureilite and carbonaceous chondrite .Among these me-teorites, 97 are ordinary chondrites, including 1 H3, 23 H4, 9 H5, 8 H6, 2 L4, 21 L5, 31 L6, 1 LL4 and 1 LL6 .Two other meteorites are olivine-pigeonite ureilite ( GRV 022888 ) and CV3 carbonaceous chondrite ( GRV 023159 ) .Some of these meteorites experienced a high degree shock , and in fact 16 members were heavily shocked samples (15 S4 and 1 S5).These heavily shocked meteorites are favorable samples for the study of early shock his-tory of asteroids .The weathering degree of these meteorites is slight , and shock effects are shown in all types but the S6 .These meteorites experienced only weak weathering .关键词
