中文摘要:根据中国大陆洋陆作用的关系和造山带的演化,重新划分了中国斑岩铜矿成矿域和成矿带,将其分为古亚洲、北部特提斯、南部特提斯(喜马拉雅)和环太平洋4个成矿域。古亚洲成矿域又分为华北陆块北缘早_中古生代成矿带、哈萨克斯坦地块东北缘晚古生代成矿带、哈萨克斯坦地块南缘中晚古生代成矿带、西伯利亚板块西南缘晚古生代成矿带。特提斯北部成矿域分为中咱地块西缘晚三叠世义敦成矿带、羌塘地块(昌都_思茅地块)北缘古近纪玉龙成矿带、塔里木地块南缘晚古生代_新生代成矿带、扬子地块西缘古近纪成矿带。南部特提斯(喜马拉雅)成矿域分为班公错成矿带和冈底斯成矿带。环太平洋成矿域分晚中生代活动陆缘成矿带和台湾古近纪_新近纪岛弧成矿带。综合分析中国大陆地质演化史与斑岩铜矿成矿地质背景,对中国斑岩铜矿勘查工作具有重要参考价值。
Abstract:According to the interplay relationship between oceanic and continental plates and the evolution of the orogenic belts of China continent, the metallogenic provinces of porphyry copper deposits in China are divided into Paleo_Asiatic, North Tethys, South Tethys (Himalayan) and Circum_Pacific metallogenic provinces. These metallogenic provinces can be further divided. The Paleo_Asiatic metallogenic province might be subdivided into Pz1-2 ore_forming belt in the northern margin of North China landmass, Pz3 ore-forming belt in the northeastern marg in of Kazakhstan landmass, Pz2-3 ore-forming belt in the southern margin o f Kazakhstan landmass and Pz3 ore_forming belt in the southern margin of Siber ian plate; the North Tethys metallogenic province into Upper Triassic Yidun ore-forming belt in the western margin of Zhongzan landmass, Paleocene Yulong ore-fo rming belt in the northern margin of Qiangtang landmass (Changdu_Simao landmass) , Upper Paleozoic_Cenozoic ore_forming belt in the southern margin of Tarim land mass and Paleocene ore_forming belt in the western margin of Yangtze landmass; t he South Tethys metallogenic province into Bangonghu and Gangdise ore-forming be lt; and the Circum_Pacific metallogenic province into Upper Mesozoic ore-forming belt of the active continental margin and Paleocene_Pliocene ore-forming belt o f the island arcs. A comprehensive study of the evolutionary history of China co ntinent and metallogenic conditions of prophyry Cu deposits would give us more v aluable reference materials.
