摘　　要：广西云开地区是广西境内铅锌金银多金属矿产的重要成矿区之一,长期以来一直是地质工作重点对象。在分析区域成矿地质背景、研究成矿地质特征、总结成矿地质规律的基础上,结合元素富集特征、典型矿床特征和找矿新发现,探讨该区域成矿远景,提出了地质找矿主要目标。结果显示,本区以构造复杂、岩浆活动强烈、基底变质程度深、成矿作用多样为特征,形成了以铅锌为优势矿种,银金为重要矿种,铜、钨锡钼等有良好资源前景的矿产地,考虑成矿地质环境因素和已知矿产分布情况,优选9个集中区,作为找矿地质工作部署的依据。As one of the important areas of gold-silver-lead and zinc polymetallic metallogenetic province in Guangxi,Yunkai region has been being the focus and object of geological work region for a long time. Based on the synthetic analyses of geological background and metallogenic characteristics as well as geological metallogenic regularity,this paper discusses the prospecting potential and suggests the most targets for exploration in the near future through the analysis of enrichment characteristics of elements,typical characteristics of deposits and the newly-discovered ore deposit. The result reveals that this region has complex structure,intense magmatism,deep basement metamorphism and active mineralization,forming an important ore-field with lead and zinc as dominant minerals,gold silver as important mineral,together with copper,tungsten,tin and molybdenum as good resource prospects of minerals. Considering with environmental factors and the distribution of known ore deposits,nine concentration areas have been selected as exploration targets in the near future.
