摘　　要：东南亚地区位于全球特提斯成矿域、环太平洋成矿域与印度—澳大利亚成矿域的交汇地带。构造演化独特,先后经历了原—古—中—新特提斯增生造山、印度—欧亚陆陆碰撞造山、太平洋俯冲等多期次构造-岩浆事件,形成了多条火山弧带、蛇绿混杂带以及同碰撞和后碰撞岩浆岩带。本文在总结前人大地构造研究成果基础上,将东南亚地区划分为6个一级构造单元、32个二级构造单元和57个三级构造单元。伴随着原—古—中—新特提斯构造演化、印度—欧亚大陆碰撞、太平洋俯冲等多期次构造域事件,以构造单元划分为基础,将东南亚地区划分为3个一级成矿域,6个二级成矿省,21个三级成矿带,并结合构造演化初步探讨了主要成矿事件。Southeast Asia is located at the intersection of the Tethys,the circum-Pacific and the India-Australia metallogenic domain.The tectonic evolution is unique in that it has experienced multi-stage tectonic-magmatic events including the Proto-,Paleo-,Meso-,and Neo-Tethys accreting orogenesis,collisional orogenesis between the Indian Plate and Eurasian Plate,and the Pacific plate subduction.These activities have developed many volcanic arcs,ophiolite belts,and post-collision magmatic belts in Southeast Asia.Based on the previous tectonic researches,this paper divides Southeast Asia into 6 first-order,32 second-order and 57 third-order tectonic units.Along with the multi-stage tectonic events including evolution of the Proto-,Paleo-,Meso-,and Neo-Tethys,the Indian-Eurasian collision,and the Pacific subduction and on the basis of the tectonic-unit division,this paper divides the Southeast Asian region into 3 first-level metallogenic domains,6 second-level metallogenic provinces,and 21 thirdlevel metallogenic belts.The main metallogenic events are discussed in combination with tectonic evolution.
