| 中文摘要: |
| 柴北缘是青海省重要的铅锌金等矿产的产区,双口山铅银矿床与区内的锡铁山大型铅锌矿床均位于柴北缘中西端,前人对锡铁山铅锌矿区做了较深入的研究,但对处于同一构造带的双口山铅银矿区研究还相对薄弱。通过对矿区内的地层、构造、矿体特征等因素的综合分析,认为双口山铅银矿床形成于华力西期,滩间山火山岩为双口山铅银矿床的矿源层；空间上区域北西—南东向断裂构造控制了含矿地层的分布范围。北东—南西方向次级断裂带控制矿体的分布。通过对矿区地质特征及控矿因素的研究,为在该区进一步找矿提供参考。 |
| 英文摘要: |
| The northern margin of Qaidam Basin in Qinghai province is an important producing area of lead, zinc, gold and other minerals. Both the Shuangkoushan lead-silver deposit and Xitieshan large-scale lead-zinc deposit are located at the western end of the northern margin of the Qaidam Basin, previous study in Xitieshan lead-zinc property has been deeply done, but that in Shuangkoushan lead-silver property of the same tectonic belt is relatively weak. Therefore, this paper comprehensively analyzes the characteristics of the strata, structure, orebody and other factors, and considers that Shuangkoushan lead-silver deposit was formed in Variscan period, and the source bed of the deposit is Tanjianshan volcanic rock. The NW -SE trending regional faults spatially controlled the distribution of ore-bearing strata, while the NE-SW trending secondary faults controlled the distribution of ore bodies. The study of geological features and ore-controlling factors could provide reference for further prospecting in this area. |
