摘要
本文概述秦岭地区区域构造演化史和多期成矿作用的特点,深大断裂带系统在成矿成岩中的重要地位,它控制了金矿的形成。秦岭地区金矿控矿构造条件是复杂的,主要有构造交汇处的剪切带。层间挤压破碎带和强烈蚀变断裂带等。还指出卡林型金矿分布极为广泛,成矿条件非常有利,在秦岭地区找金前景是乐观的。
This paper gives a general account of the history of tectonic evolution and features of multi-stage mineralization in the Qinling region, The deep fault system occupies an important position in rock and ore formation. It has controlled the formation of gold deposits. The gold-controlling structures in the region are complex, mainly including shear zones at the intersection of structures, interlayer compressive fracture zones and strongly altered fault zonese It is pointed out that Carlin-type gold deposits are very widespread and that ore-forming conditions are very favourable there, so gold prospecting in the Qinling region is promising.
