 the Indian Australian Plate and the Pacific plate, experienced complicated tectonic evolution process since Late Cretaceous. Plate convergence, collision, subduction, detachment and spreading caused to form geologic tectonic units characterized by southern craton, central fold belt and northern island arc beet in the area, forming the metallogenic system with characteristics of the passive continental margin, being importantly significant for the ore prospecting of copper –gold deposits of porphyry and epithermal types and nickel deposit of lateritic type.
