摘要
在野外调查基础上,本文结合前人研究成果总结了双尖子山银铅锌矿床成矿规律,认为矿床具有叠合成矿特点,经历了与燕山中期深源浅成侵入体有关的铅-锌-银矿化和与晚侏罗—早白垩侵入-火山杂岩有关的银多金属矿化过程,地层、构造及岩浆作用共同控制矿体的形成。指出矿区找矿应注重火山机构的研究、激电异常验证和高中温热液成因锡铜矿找矿三方面工作。
Based on field investigation and previous researches,this paper summarizes the metallogenic regularity of the deposit.The result shows that the deposit is characterized by superimposed mineralization,which may have experienced lead zinc silver mineralization related to the middle Yanshanian deep source hypabyssal intrusion and silver polymetallic mineralization related to the late Jurassic Early Cretaceous intrusive volcanic complex;The formation of ore body is controlled by stratum,structure and magmatism;The future work should pay attention to the verification of volcanic institutions,IP anomalies and the exploration of high and middle temperature hydrothermal tin copper deposits.
