摘　　要：利用广西云开地区1∶20万化探扫面成果,研究该区成矿元素的地球化学特征及分布规律,并选择了主要成矿元素Ag、Au、Pb、Zn、W、Mo、Sn进行讨论,研究它们在空间、时间上的分散、富集规律,为区域矿床地球化学预测提供理论依据;提出Ⅰ级找矿远景区8个,Ⅱ级远景区5个,Ⅲ级远景区3个,作为下一步矿产勘查工作的靶区。Using the results of 1 ： 200 000 geochemical exploration, this paper described the geochemical characteristics and regularity of of metallogenic elements distribution in Yukai area,and discussed the key elements that should be selected, such as Ag, Au, Pb, Zn, W, Mo and Sn. This paper sums up the spatial and temporal distribution regularity of elements dispersion or accumulation in order to provide geochemical theoretical basis for the prospecting of regional mineralization. The target areas for farther exploration are deline- ated, which include 8 Grade I , 5 Grade II and 3 Grade III prospective areas.
