| 摘 要： | 三江地区单凭“一次造山”是难以圆满解释的。本文试以“多次造山”多期成矿”的思路作出合理说明。晚古生代－中生代早期多岛海造山阶段，羌塘弧、江达弧和临沧弧应为前锋弧，其后由一系列弧后盆地和岛弧或残余弧（或微大陆）组成。中生代中－晚期为陆内俯冲造山阶段，推测金沙江带、哀牢山带和龙门山－锦屏山带为俯冲主边界，从而形成本区燕山期重熔型花岗岩带，控制相应矿产的分布特征。新生代陆内转换造山阶段，造成特征的构造－岩浆－成矿带，具有生成大型或超大型矿床的潜力。

| Abstract: | Geology of Jinshajiang Lancangjiang Nujiang region in Southwest China cannot be interpreted only on the basis of "one orogenesis". An interpretation of "polyphase orogensis" and "polyphase metallogenesis" has been proposed in the paper. During Late Palaeozoic Early Mesozoic archipelago orogenic Stage, Qiangtang. Jomda and Lincang arcs should be frontal arc, behind which a series of back arc basins and island arcs or remnant arcs(or microcontinents)was distributed. In Middle Late Mesozoic orogenic stage of intracontinental subduction, Jinshajiang, Ailaoshan and Longmenshan Jinpingshan belts may be main intracontinental subduction zone, which caused Yanshanian remelting granites and controlled distribution of mineral resources. Entering upon Cenozoic stage of intracontinental transform orogenesis, characteristic tectonic magmatic metallogenic zone was developed, which has a potential for formation of large or superlarge deposits. |
