Abstract: Neo-proterozoic metamorphic and intrusive rocks(bodies)are discovered in Nalinggelehe area in East Kunlun, which were intruded into Jinshuikou Paleo-proterozic rock group and Wanbaogou Mesoproterozoic-Neoproterozoic rock group, with the lithology of granodioritic gneiss and monzonitic granitic gneiss. The LA-ICP-MS zircon dating of granodioritic gneiss has yielded an age of (840±2)Ma, which belongs to the Neo-proterozoic era.Rock geochemistry shows the characteristics of strong peraluminous, high potassium calc-alkaline series rock, with the features of S type granite, which was formedin continental collision orogenic environment and served as a product of the collision environment.This age and the available dating data suggest that a Meso-to Neo-Proterozoic granitic intrusive belt exists in the eastern margin of the Kunlun block, and that the whole Kunlun block might be a response to the amalgamation event of global Rodinia supercontinent.
