摘　　要：随着分形理论的建立与发展,应用分形理论研究矿床分布及元素的分布与富集规律已经成为研究成矿作用的一个有力的新工具。分析了水口山铅锌金多金属矿田各已知控矿断裂带、潜在控矿断裂带及区域地层和矿区花岗岩体的元素含量分布的分形特征。结果表明,断裂带内的元素分布有两个地质过程控制,即经受了后期改造叠加作用,且部分活动性较强的元素和Cu,Pb,Zn等成矿元素,富集程度高,取代或者掩盖了元素的原生分布规律。而地层和花岗岩体的元素分布则没有受到后期的断裂活动的改造作用。此外,F5,F16断裂带也有较好的找矿前景。Along with the arising and developing of fractal theory, it has become a new powerful tool on study of mineralization through fractal analyses of distribution of deposits and elements. Fractal analyses of element content of fracture zone and stratum in Shuikoushan Pb-Zn-Au polymetallic ore field in Hunan Province, China have been done in this paper. It indicates that stratum and granite body can only show the original element distribution but fracture zone show two geological processes control the element distribution. The deuteric superposition processes increase the enrichment of some high activity elements. Furthermore, the little fractal value can show mineralization and F5 ,F16 fracture zones show a good ore prospecting foreground.
