| 中文摘要: |
| 本文综合野外最新地质资料及室内研究进展,对柴北缘地区首次发现的产于中酸性岩体中的以石英脉型矿石为主的三角顶金矿床的地质特征进行了总结,分东、西两个矿区分别对受控于花岗闪长岩体中张剪节理裂隙控制的石英脉型矿化体和受北西向构造蚀变带控制的硅化糜棱岩型矿化体矿化特征进行了研究,对比分析了两种矿石类型的异同点。结合区域成矿事件,建立了该矿床的成矿模式,初步认为该矿床为受多期成矿作用影响的造山型金矿床叠加岩浆热液型矿床,提出了区内找矿标志。 |
| 英文摘要: |
| According to the field geological data and the results of indoor consolidation research, the geological characteristics of the deposits at the SanJiaoding gold deposit are summarized and divided into two mining areas in the east and west. The quartz vein type mineralized bodies controlled by the gash joint fissures or the shear joint in the granodiorite and the silicified mylonite-type mineralized bodies controlled by the NW-trending structural alteration zone were separately studied. And the similarities and differences between the two ore types were compared and analyzed. Combined with the regional metallogenic events, the ore-forming model of the ore deposit is summarized. It is preliminarily believed that the ore deposit is a magmatic hydrothermal type of orogenic gold deposits affected by multi-stage mineralization, and a prospecting indicator is established in the area. |
