中文摘要：
通过介绍激电中梯法和高精度磁测法在多不杂矿段的找矿实践，分析和总结了矿区内地球物理场特征与矿体之间的关系。结果表明，在矿体附近激电异常特征表现为低视电阻率和高极化率，并且随着矿物中金属硫化物含量的增加，极化率也增高；矿体上高精度磁测异常特征表现为低磁正异常。总体来看，矿区内物探异常围绕花岗岩岩体及接触带附近分布，套合良好，真实反映了含矿花岗闪长斑岩体及矿化蚀变分布范围，为今后多龙矿区内寻找铜金矿床提供了地球物理场特征。
英文摘要：
The relationship between the characteristics of geophysical field and the ore body in the mine was analyzed and summarized by introducing some prospecting practices which were used induced polarization gradient technique and pre- cision magnetic measurement methods in Duobuza ore segment. The results show that IP anomalies characteristics is low ap- parent resistivity and high chargeability near ore body, and the polarization rate increased with the increase of metal sulfide content in the minerals. Ore bodyg abnormal characteristics of precision magnetic survey are low magnetic normal anomaly. Overall, the mine Geophysical anomalies distribute around the granite rock mass and the contact zone, and reflect the Ore granite porphyry and Mineralized alteration distribution range. The results provide the characteristics of geophysical fields to look for copper-gold deposit in Duolong in future.
