Discovery and Geological Significance of Metamorphic and Intrusive Rock (System) of Kayakedengtage Region Intruded Into Jinshuikou Paleo-proterozic Rock

Abstract

Metamorphic intrusive rocks (bodies) into Jinshuikou rock group of the Paleo-proterozic were found. The isotope age determination shows they are the Neo-Proterozoic. The metamorphic intrusive rocks (bodies) derived with aluminum calcalkaline series, and resulted from a tectonic environment of synchronous collision. The discovery of metamorphic intrusive rocks (rodies) has important significance to a thorough invest-tigation and study of Presinian period basement in the west of eastern Kunlun Mt. And it is of great significance to resume or confirm the developing and evolvement history of Qimantage tectono-magma belt.
