摘要
大南金矿矿石类型有石英脉型、构造角砾岩型以及蚀变破碎板岩型三大类型,赋存于中元古界冷家溪群地层中,矿脉受北东向韧性剪切带的构造作用控制,次一级的北北西、近东西向的断裂是控矿、容矿构造,此论文在在分析大南矿区的地层、构造、岩石、及矿体等地质特征和成矿成因探讨基础上初步提出了成矿富集规律,对研究此类金矿床找矿具有一定的指导意义。
The ore types of Dainan gold deposit are quartz vein type, tectonic breccia type and alteration crushing slate type, which occur in the Mesoproterozoic cold house strata formation, The tectonic action of the strata is controlled by the geologic characteristics of the strata, tectonics, rocks and ore bodies in the Dainan mining area. Which is based on the study of the causes of ore deposits, and it is of great significance to study the prospecting of this type of gold deposit.
