摘　　要：通过对广东省核工业地质局二九一大队承担的“粤西北地区找矿选区与评价”项目中粤西北西江-黎埠地区10条岩石地球化学剖面特征进行分析,发现区内主要富集元素是Mo、U、Cu、Sr、Sb、Be;其中Mo、U、Cu、Sb、Sr等元素富集系数较高,具有较好的成矿前景;U在石炭纪梓门桥组中表现出高度富集的特征,与区内存在较好的灰岩、砂岩层间破碎带型U矿化吻合;区内14个元素在R型聚类分析显示出较好的共生组合关系。The characteristics of 10 rock geochemical profiles in the Xijiang-Libu area of northwest Guangdong Province obtained in the project of‘mineral prospecting area selection and evaluation in northwest Guangdong Province’undertaken by 291 Brigade of Guangdong Province Nuclear Industry Geological Bureau are analyzed,and it is found that the main enriched elements in the area are Mo,U,Cu,Sr,Sb and Be.Among them,Mo,U,Cu,Sb,Sr,etc.have high enrichment coefficients and good mineralization prospects.U shows the characteristics of high enrichment in the Carboniferous Zimenqiao Formation,which is consistent with the presence of good interlayer fracture zone type U mineralization in limestone and sandstone in the area.The 14 elements within the area show good symbiotic relationships in R-type clustering analysis.
