摘　　要：西秦岭李坝式金矿床赋矿空间为中川岩体热晕范围内的多级构造体系,成矿时代与燕山期花岗岩侵入时代相近.稀土元素及流体包裹体特征显示其成矿物源与沉积建造具有更大的亲缘性,同时也体现了岩浆活动的痕迹.Multiple grade folds and faults systems around Zhongchuang granite heat scope are the mineralizing spaces of Liba-style gold deposits in west Qinling. The mineralizing age is nearly to the age of Yanshanian granite. Characteristics of REE and fluid inclusions show that ore-forming materials have a close affinity with sedimentary formations, but the traces of magma activities are also reflected by them.
