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.
