| 摘 要： | 深入研究郝泉沟金矿床的控矿构造特征，以指导其深部及外围地质找矿，增加地质储量，为矿山的可持续发展奠定基础。二云斜长花岗岩岩体内节理、断裂发育，可划分为成矿前及成矿构造。控矿构造主要为NNE向断裂，具有明显的双重结构面特征，金矿体严格受其控制。它们是由花岗岩的成矿前构造经多期次、多阶段构造运动和热液交代作用形成。

| Abstract: | Joints and faults are well developed in muscovite biotite plagio granite, which can be divided into promineralization and postmineralization structure. The ore controlling structure is mainly NNE strike fault with double constructional surface. They are formed by polyperiod and multistage tectonic activity and hydrothermal metasomatic process of the promineralization structure. |

| Keywords: | gold deposit ore controlling structure constructional surface Gansu |
