英文摘要	It has been proved that the Jinyanshan granodiorite, which outcrops at the southern side of the Hongliugou-Lapeiquan ophiolitic melange zone in the northern part of the Altun Mountains, developed in the Andean-type arc tectonic setting by studied on its lithological and lithogeochemical features, and its formation age (467.1 +/- 6Ma) has been gained by single zircon U-Pb isotopic dating of the granodiorite. In addition, we have also gained Ar-40/Ar-39 plateau age (455 +/- 2Ma) and isochrone ages (450 +/- 11 Ma) of sericite from sericite-quariz-schist within matrix in the Hongliugou-Lapeiquan ophiolitic melange zone. These results above indicate that Jinyanshan collisional orogenic belt developed during the early Paleozoic, and the ocean-continent subduction took mainly place during the early to middle Ordovician and the continent-continent collision occurred during end of the middle Ordovician.
