| 摘 要： | 小柳沟铜钨多金属矿田是我国西北大型钨矿的典型代表,其矿体受构造控制明显:背斜层间滑动虚脱构造控制了主矿体的形态、规模和产状,隐伏岩体侵位构造控制了区内矿床(点)的分布,岩性层构造裂隙的发育程度控制了矿体的富集.上述3种构造作用表明在小柳沟和祁宝矿床之间及世纪矿床西部外围地段有望找到新的矿体.

| Abstract: | Xiaoliugou Cu - W deposit is a typical representative of large Cu - W deposit in the northwest China. Orebodies are obviously controlled by structures. Intedayered detachment structures of anticline control shape, scale and occurrence of main orebodies, and intrusive structure of concealed magma control distribution of deposits or spots. Enrichment of orebody is controlled by extent of fractures in the layer. It is proposed that new orebodies can be found between Xiaoliugou and Qibao deposit, as well as in the west of Shiji deposit. |

| Keywords: | interlayered detachment structure of anticline magma intrusive structure lithologic layer fracture Xiaoliugou |
