Characteristics of metamorphic intrusion in Qinling complex

Lianghekou lithosome is a metamorphic intrusion and extracted from Qinling complex based on the Fengxian Taibai 1:250 000 geological mapping. The zircon isotope age is 851.8±1.9Ma. According to the petrologic and lithochemical character, there is Jinning continental arc granite along the Shangluo-Danfeng of North Qinling orogenic belt. And it can compare with the lithosome of Caiao and Dehe in East Qinling area. The confirmation of the Lianghekou lithosome provides a new evidence to the existing of Jinning movement,its moving characteristics and the form of Rodinia supercontinent.
