摘要
招平剪切带相关矿化类型主要有破碎蚀变岩型和石英脉型,其容矿部位一般遵循里德尔单剪模式。其演化一般表现为早期阶段的毒砂富集,中期阶段形成微细金,晚期形成颗粒金。提出加强寻找招平断裂的次级断裂及高角度断层的成矿研究,加大寻找与绿片岩相变质环境一致的矿物组合地段以及CO_2/CH_4、H_2O/CO_2比值低的异常部位进行重点探矿。
The relevant mineralization types of Zhaoping shear zones mainly include fracture altered teetonite-type and quartz vein-type, and the ore-hosting site generally follows Riedel Single-shear mode, also the evolution shows early stage of arsenopyrite enrichment, medium-term stage of the formation of fine gold and the late stage of gold particles. This paper proposes strengthening to find the secondary faults of Zhaoping fault, and metallogenic research of high angle fault, seeking the mineral assemblage lot consistent with the greenschist facies metamorphic environment, as well as abnormal sits with low ratios of CO2/CH4 and H2O/CO2 to carry out focused prospecting.
