| Abstract: | s Yuejinshan complex is composed of weakly metamorphosed and strongly deformed rocks, granitoid and basic-ultrabasic rocks, which were originated from continental margin or island arc. Due to the high-pressure hornblendes and the jadeite, it is reasonable to be proposed that Yuejinshan complex had once experienced low temperature and high pressure metamorphism. The basic-ultrabasic rocks and Raohe ophiolites have been studied in detail, they are formed in different tectonic environment. Yuejinshan complex is the accretional complex which was formed during Yuejinshan terrane collision and accretion. According to the evolution history, a Mesozoic tectonic evolution model of the northeast Asia has been proposed, which includes following three stages: compressional subduction, extensional subduction and transform fault. |
