摘　　要：在野外地质调查的基础上,对新疆东准噶尔南明东金矿床的矿床地质特征、成因类型、控矿因素、找矿标志以及下一步找矿方向进行了综合研究,认为该矿床为中低温热液蚀变岩型金矿床,受韧脆性剪切带、地层建造和热液活动的多重控制。矿区地质环境复杂,地表蚀变带规模较大,深部尚未完全控制,具有较好的找矿前景。南明水组的层间断裂、褶皱交汇部位是成矿的有利地段。On basis of field investigation,comprehensive study was carried out on geological characteristics,genesis,ore-control factors,prospecting criteria and the future prospecting direction of Nanmingshuidong Au deposit.We consider that it is a meso-epithelial altered rock type Au deposit controlled by ductile-brittle shear zone,strata and hydrothermal activities.The geological setting is complicated at surface.Alteration spreads in large area.The ore at depth is not controlled thus potential for further prospecting.The future prospecting should be directed to the favorable metallogenic localities of inter formation fault zone of Nanmingshui formation and the folds`cross.
