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.
