摘　　要：以二道桥地区1∶10 000土壤地球化学测量、高精度磁测、激电中梯等原始数据为基础,综合分析了测区的物化探异常特征、探槽和钻孔原生晕特征,探讨了探槽和钻孔原生晕元素比值特点,推测了矿体产状和大致形态,以及在空间上的成矿部位,预测了Cu、Pb、Zn、Ag成矿元素的有利地段,提出了两个找矿重点区域。Based on the primary data of geochemical soil survey, high precision magnetic survey and the IP of the ladder on a scale 1：10 000 in Erdaoqiao area, the authors analyzed the detailed characteristics of geophysical and geochemical anomalies, exploratory trench holes and drilled primary halo, discussed the element ratios characteristics of primary halo, and deduced the attitude and possible form of orebody and the metallogenic places. The favorable location of metallogenic elemeny of Cu, Pb, Zn, Ag, and two prospecting areas have been forcasted.
