| [摘要]柳坝沟金矿区位于华北地台北缘西段,产于太古代乌拉山群变质岩系中,矿床主要矿石
类型为钾长石-石英脉,钾长石化是最发育的近矿围岩蚀变,与金矿成矿作用关系密切。利用对钻孔地
球化学元素的分析研究,313 号脉具有多期多阶段叠加成矿成晕的特点,根据不同成矿阶段元素组合和
单阶段形成原生晕的垂直分带规律及不同成矿阶段形成矿体(晕) 在空间上的叠加特点,建立了矿床的
原生晕叠加晕模式,对主要矿脉进行了深部预测,最后利用钻探工作验证,取得了较好的地质效果,为该
区深部探矿起到指导作用。 |

| Abstract:The Liubagou gold deposit is located in the western margin of the North China platform. It was formed in the Archean metamorphic rocks
in the Ural Mountains Group, with the primary ore types of K-feldspar-quartz vein. The K-feldspar mineralization is the most developed of near-ore wall
rock alteration in close relation to gold mineralization. By use of drilling data, geochemical analysis of elements suggests that the vein No. 313 is character鄄
ized by multi-stage stacking of halo and ore generation. According to combination of elements from different ore-formation stages, vertical zonation of sin鄄
gle-stage primary halos, and of vertical zoning laws and superimposed orebodies (halos) of different stages, we established a model of superimposed origi鄄
nal halos for the deposit and predicted the main veins at depth. Finally drilling was used to confirm the model and preciction, yielding a good geological
result which is helpful to exploration toward depth in this area. |
