摘　　要：通过对西大明山—大瑶山构造—岩浆隆起带的系统观测 ,获得了各区域地质体金银成矿元素的初始丰度 ,文章利用最近完成的区域内各 1∶5万区调地层剖面数据并补充实测的若干区域地化剖面数据 ,给出了区域基岩地球化学场及其结构的基本面貌 ,结合区域地质背景对金银成矿元素地球化学特征及地质意义进行分析总结。Based on systematic geochemical observing on Xidaminshan-Dayoushan upwarping fold zone, the Au-Ag ore-forming elements' abundance of regional geological units was acquired; According to the standard geological profile's data of the regional geological surveying on the scale of 1:50 000 and regional geochemical profiling of Xidaminshan-Dayonshan upwarping fold zone, the authors described the characteristics of the regional rock geochemical field and structure, and the geochmical characteristics of Au-Ag ore forming elements and geological significance is also summarized.
