摘　　要：吴川—四会断裂带是广东境内一条重要的北东向构造带,控制了一系列大型、超大型矿床的分布,具有良好的金、铁、铅、锌矿找矿前景。基于该断裂带四会市石狗地区和英德金门地区水系沉积物测量的12种元素原始测量数据,分析了水系沉积物元素分布及组合特征,并对同一断裂带同类型地质体不同的元素地球化学特征的成因进行了探讨,为该断裂带有色金属矿产靶区优选、资源潜力评价及研究不同地球化学块体元素迁移富集规律提供参考。Wuchuan-Sihui fault zone is an important North-east structural belt in Guangdong Province,and has the distribution of a series of large and super large deposits,which contain gold,iron,lead and zinc.Based on the original measurement data of 12 elements measured in the stream sediments of Shigou area of Sihui City and Jinmen area of Yingde City,this paper analyzed the element distribution and combination features of the stream sediments,and discussed the genesis of geochemical features of the different element in the same type geological body in the same fault zone.This article provided a reference for the selection of nonferrous metal mineral target areas and the evaluation of resource potential in the fault zone,and studied the migration and enrichment of elements in different geochemical blocks.
