在现代新构造学和成矿地质理论的指导下,以前人工作的研究为基础,重点对区内赋矿地层、矿脉特征、成矿条件及构造成矿方面做了深入的分析。提出了本区冷家溪群是矿源层,并且成矿物质不仅仅来自于围岩,还有一部分来自于地壳深部岩浆侵入;控制金矿田的是近EW向的3条区域韧性推覆剪切带,控制金矿体的是一些低次序在剪切带基础上的扩容断裂构造;金矿成矿与剪切变形存在密切的时空关系,长时间的强烈的剪切变形,不仅使矿体和围岩强烈变形,而且促使了成矿元素的高度富集;黄金洞金矿田矿脉主要分布在韧性剪切带上,因此今后主要工作在于寻找东西向的韧性剪切带。
Under the guidance of modern neotectonics and metallogenic geology theory, based on the previous work of the authors, the paper deeply analyzes the strata and vein characteristics, metallogenic conditions and tectonic mineralization in the area. It is proposed that Lengjiaxi Group in this area is the source rock layer, and the ore-forming materials are not only from the surrounding rock, but also partly from the deep magma intrusion into the crust. Controlling the gold ore field is the three areas near the EW, Belt-cutting and controlling of gold ore bodies are some of the low-order expansion-fault structures on the basis of shear zones. There is close temporal and spatial relationship between gold mineralization and shear deformation and intense shear deformation for a long time. And the strong deformation of the surrounding rock, and prompted a high degree of enrichment of metallogenic elements. The gold veins of the gold deposit are mainly distributed in the ductile shear zone, so the main work in the future will be to search for the east-west ductile shear zone.
