摘　　要：综合物化探测量成果显示,东川地区隐伏断裂构造上方或夹持区内,多测段210Po呈增高或异常的双峰、多峰形态,显示土壤层中形成有一定宽度的增高或异常分散晕,存在局部210Po富集,且与高阻-高极化或低阻-高极化的地电异常相对应。结合区内铀成矿地质条件和已知铀矿化地段210Po异常峰特征,综合分析测区内找铀矿前景,预测、划分了成矿有利地段。Comprehensive geophysical-geochemiscal survey found that polonium-210 activity of several measured sectors have high increased or double-mulit peak shape anormaly in the structure cramp area above the concealed Dongchuang structure,which suggests that there was high valued or dispersed halo of polonium anomaly with some width in the soil.This geochemical anomaly was correspond to that of geoelectric anomaly of high resistivity（ρS）-high polarizatility（ηS） and low resistivity（ρS）-high polarizatility（ηS）.Combining the character of polonium-210 anomaly peak feature to known uranium mineralization sector and metallogenic conditions in the area,the exploration prospect was analyzed and the favorable ore forming sector was prognosticated and divided.
