摘　　要：西秦岭中川花岗岩为3期5次侵入的复式岩体,其主侵入体为印支—燕山期黑云母同碰撞S型二长花岗岩。该岩浆活动在沉积建造中形成热变质作用带和岩浆侵位构造,并产生成矿地质效应。Zhongchuan granite of western Qinling area is a granite complex.Its principal intrusion is Indoyanshanian S-type biotite adamellite.Magmatic activity led to the formation of thermo metamorphism belts and to the magmatic intrusive structures and at the same time produced geological effects.
