摘　　要：1.Objective The formation of East Gondwana and its combination with West Gondwana is a result of a series of complex orogenic events,known as Pan-African orogeny.The Northern Qinling Mountain is a microcontinent that formed on the ancient oceanic crust in the northern of Yangtze craton before Neoproterozoic.It is likely that the North Qinling,even the Yangtze craton and its surrounding oceanic crust belong to the ancient Gondwana tectonic domain and be a part of East Gondwana supercontinent(Chen Q,2007).
