| 中文摘要: |
| 双元沟—池沟地区位于南秦岭礼县—柞水华力西褶皱带东段,凤镇—山阳大断裂近北侧,区内发育与燕山期斑岩体相关的斑岩型铜钼矿床,矿体赋存于斑岩体及其与围岩的接触带中。通过对该区成矿地质特征进行综合分析,认为矿体主要受岩体、蚀变类型、构造叠加、地层等因素控制。沿区内斑岩体群依次向外可将成矿类型划分为斑岩型、夕卡岩型、构造—热液型,它们共同构成斑岩型矿床的成矿系列,因此,在该区寻找斑岩型铜钼矿床的同时,应当注意夕卡岩型铜矿、构造热液型金银矿的评价。 |
| 英文摘要: |
| The Shuanghyuangou-Chigou area is located in the eastern part of the Hercynian folding belt of Lixian-Zhashui in the Southern Qinling orogenic belt and the northern part of Fengzhen-Shanyang fault. The porphyry type copper and molybdenum deposits related to porphyry intrusions of Yanshan period are widely distributed in the region, the ore bodies are hosted in the porphyry and the contact zone between of the porphyry and surrounding rocks. Through the comprehensive analysis of the metallogenic geological features in this area, it is thought that the orebodies are controlled by intrusion, alteration type, tectonic superposition and strata etc.. The metallogenic types can be divided into porphyry type, skarn type and tectonic hydrothermal type from the inside porphyry to the outside zone which constitutes the metallogenic series of porphyry type deposit. Therefore, it should pay attention to the prospecting of skarn type copper deposit and tectonic hydrothermal type gold and silver deposit while exploring porphyry copper and molybdenum deposit in the district. |
