| 中文摘要: |
| 桥头花岗岩矿区位于滦平县城东北约35 km处,在开采建筑石料用花岗岩的同时发现了与之共生的4条金矿脉。建筑用花岗岩矿赋存在海西期花岗岩体内的燕山晚期中粗粒花岗岩中,矿体呈透镜状,厚度130～145 m。金矿脉则赋存于海西期花岗岩体的4条NNW向断裂带中,表现为燕山晚期含金石英脉体充填和脉体两侧呈浸染状、细脉状黄铁矿交代。大庙—娘娘庙深断裂、古北口—平泉深断裂控制了该区地层、构造和岩浆岩的分布,金矿床主要受低序次NNW向断层的控制,既是导矿构造,又是容矿构造。 |
| 英文摘要: |
| Qiaotou granite mining area is located 35km in the northeast luanping county. Four gold veins in the granite were discovered in association with it. Granite ore for construction occurs in late Yanshanian medium-coarse grained granite intruding into Hercynian granite body, and the ore body is permeable with a thickness of 130～145m. Gold veins occur in 4 NNW fault zones of Hercynian granite bodies, which are characterized by filling of auriferous quartz vein bodies in late Yanshan period and disseminated and veined pyrite metasomatism on both sides of vein bodies. Damiao-Niangniaoshen fault and Gubeikou-Pingquan deep fault control the distribution of strata, structures and magmatic rocks in this area. Gold deposits are mainly controlled by low-order NNW faults, which are both ore-conducting structures and ore-hosting structures. |
