摘要: Meteorites are extremely valuable in providing clues about the origin, evolution, and composition of Sun, Moon, Earth, other planets, asteroids. Since first discovery a meteorite Antarctica, more concentrations on bare ice stranding sites were discovered. Antarctica is identified as prolific source extraterrestrial materials. The Grove Mountains area, covered by ice, snow, nunataks, located Antarctic inland area. It 380km away from Chinese Zhongshan Research Station East Antarctica. 1998, 11,452 meteorites have been collected National Expedition (CHINARE). confirmed that area productive search for More recoveries led to recognition unique mechanisms relating exist Besides field collections, extraction blue based satellite images, concentration mechanisms, data distribution service discussed this paper. Wide indicates enrichment meteorites. Based different spectrum characteristics coherence rocks, areas extracted optical images maps. According collections moraines also theories should be further analyzed taking into account ice-flow dynamics, mountains' blocking effect, katabatic wind ablation, others. Moreover, order strengthen visualization network sharing data, desktop software ArcObjects web ArcIMS developed within study. enables analysis Mountains.
