卡林型金矿是产于沉积岩及浅变质沉积岩的中低温热液型金矿，也是广西右江地区重要的金矿类型之一。右江褶皱系金矿体赋存层位主要为泥盆系和三叠纪碳酸盐岩及陆源碎屑岩，区内构造复杂多样，相互交错叠置，对卡林型金矿的成矿起着重要作用。研究发现，右江地区具有较高的Sb、As和Hg背景值，该元素异常的重合地段是重要的找矿靶区，Sb、As和Hg也是卡林型金矿产出的重要指示元素。通过分析该区成矿条件，指出右江地区卡林型金矿床赋存的有利场所是台缘断裂与覆盖于碳酸盐孤台之上的含钙杂砂岩层和古土壤层的交切部位，深大断裂的旁侧和大的岩相分界线是最有利的找矿方向。目前，已在矿区内圈定出4处成矿远景区。

The Carlin-type gold deposits in sedimentary rock and shallow-metamorphic sedimentary rock are medium-low temperature hydrothermal type which is also one of the important type of gold deposit in Youjiang area of Guangxi Province.The occurrence horizon of Youjiang fold system of gold ore body is mainly carbonate rocks,terrigenous clastic rocks from the Devonian System and Triassic.The structure complicated and diversed and superimposed plays an important role in gold mineralization of the Carlin-type gold deposits.The study suggests that quite high Sb,As and Hg background value is presented in Youjiang area.Overlaping sections of the anomalous elements are not only the important prospecting target areas but also an important indicator of the Carlin-type gold deposits.Through the analysis of metallogenic conditions in Youjiang area the paper points out that the benefit places of occurrence horizon of the Carlin-type gold deposits are intersection parts constituted the platform margin fracture and calcium complex sandstone layer covered in the carbonate platform margin of solitary and soil layer.The beside of deep fracture and big lithofacies interface is the most forceful prospecting direction.At present,4 prospective metallogenic areas were framed out within the mining area.
