摘要
川西北微细浸染型金矿集中区,金成矿带及金矿床明显受构造的控制。从区域成矿地质背景及控矿因素来看,大地构造环境制约着"矿源层"及赋矿地层的形成,区域断裂构造控制着金成矿带及金矿床的空间分布。川西北地区金矿矿田构造规律的研究表明,金矿化局部富集主要发生在断裂产状变化部位、两组断裂的交汇部位以及碎裂岩与构造透镜的接合部位。
In the northwestern Sichuan Province,a major distribution area of fine disserminated gold deposits consisting of dozens of gold deposits have been found.The formation and distribution of gold-deposits were controlled by tectonic setting in the area. The gold deposits controlled by ore-forming structure were discussed in this paper.It showed that the concentration of gold occurred in the variation position of attitude of faults,at the intersection position of two sets of faults and at the intersection of structural lens and cataclasite.
