| 摘 要： | 巴布亚新几内亚在大地构造位置上位于欧亚板块、印度-澳大利亚板块和太平洋板块的结合部位.本文介绍了自晚白垩世以来巴布亚新几内亚经历的复杂地质构造演化过程,不同板块间的汇聚、碰撞、俯冲和拆离、扩张等地质作用形成了以区内南部克拉通、中部褶皱带及北部岛弧带为特点的地质构造单元,在区内形成了具有活动大陆边缘特色的成矿系统,对寻找以斑岩型和浅成低温热液型铜金矿、红土型镍矿为主要成矿类型具有重要意义.

| Abstract: | Papua New Guinea, which is located at the triple joint of the Eurasian plate, 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. |
