| Session Description | In the last few years, the effects of tectonic processes on the emplacement of magma and generation of ore deposits from ocean floor spreading to subduction and collision-related environments are increasingly discovered and documented. Seafloor related deposits such as VHMS deposits are formed during the rifting of oceanic ridges or back-arc basins and related to specific magmatic processes. Continental ore deposits such as porphyry copper deposits are formed in time and space as clusters, coinciding with particular tectonic processes related to episodes of flat slab subduction or collision of intra-oceanic island arcs and continental margin. The East and SE Asia region is characterised by an assembly of crustal plates or microcontinents that were rifted off from northern margin of Gondwana during Phanerozoic. These microplates or terranes were drifted on the Tethyan Ocean northward and accreted or collided with the Eurasian margin. During these rift, drift and assembly, various subduction and collision/post collisional processes are responsible for a diverse and abundant formation of minerals from gems to future metals such as REE and Li, and other ore deposits in East and SE Asia, However, the knowledge of various tectonic events and related magmatic processes and metallogeny in the region are poorly documented. The aim of this session is to improve the understanding of the tectonic evolution and metallogeny of East and SE Asian region. The main topics that will be covered in this session are: (1) Subduction- and Collision-related tectonics and assembly of Gondwana, (3) Intra-plate deformation in Asia, (4) Tectonics and deformation along Eastern Asian continental margin, (5) Metallogensis and mineral potentials, (6) Geochemistry and genesis of ore deposits in East and SE Asia and (7) Recent geochemical, isotopic and geochronological studies of mineralized Fold Belts in the region. This particular session will invite various group of petrologists, sedimentologists, structural geologists, geochemists, geochronologists and economic geologists working in Asia to offer their results and knowledge to make a better understanding of tectonic processes linking magmatism and metallogeny of the region. |
