Abstract
Disintegration of Jinningian metamorphic intrusive rock of Kumabbyhz region,invaded the ancient Paleoproterozoic Bai Shahe Formation and Jixian system Lang yashan Formation,this paper based on isotope results of sample,confirmed its era is Neoproterozoic,and magma result from the upper crust,it is the production of late collision of Neoproterozoic orogen environment.Discussed geochemical characteristics of this period intrusive rocks,there is great significance for further study of early Sinian basement of Kumabbyhz areas in east Kunlun and restore and establish Qimantage tectonic magma development and evolution history.
