SE Asia is an assembly of Gondwana-derived crustal blocks, and an important piece for the geodynamic understanding of the Asian continent. Since the Phanerozoic, this area experienced several significant geodynamic events. The separation of many continents and microcontinents from Gondwana through rifting lead to the opening of oceanic domains. The closure of these oceanic basins and the subsequent continental collision is attested by subduction related magmatism, accretionary complexes, high-pressure and high-temperature metamorphisms, crustal melting and magmatism including volcanism and plutonism. The Mesozoic tectono-magmatism, the Cenozoic intracontinental tectonics related to the India collision, and the recent magmatism and tectonics are also significant events recognized in SE Asia. These geodynamic events represent the general framework for the numerous ore deposits recognized in the area.
