广西福海山地区物探测量结果及其解释

简要介绍了高精度磁测、210 Po法和EH-4电导率成像系统的工作原理。通过对已知矿床剖面试验成果分析解释,发现在铀矿体上方地表存在负磁异常和210 Po异常。把福海山地区高精度磁测和210Po法面积测量结果与已知矿床剖面试验成果进行对比分析,圈出了铀矿化区和断裂构造F1、隐伏断裂F0的分布特征,并采用EH-4电磁测深进行验证。说明利用高精度磁测和210 Po法可以有效地推测出测区构造、断裂带的分布范围,为矿区矿化地段深部找矿工作提供有利的勘查区域范围,为下一步的普查工作提供了可靠的地球物理依据。

Geophysical Survey Results and Their Interpretation in Fuhaishan Region,Guangxi

This article briefly introduces the working principle of high precision magnetic survey, 210po method and EH-4 conductivity imaging system. By analysising the test results and interpretation of the known deposits profile, it was found that there is a negative magnetic anomalies and 210po anomalies a- bove the surface of the uranium ore body. In Fuhaishan area determined result of high precision magnetic method and 210 Po were used to compare the known deposit profile. The area of uranium mineralization and faults F1, concealed fracture F0 distribution characteristics were delineated and validated with the EH-4 electromagnetic sounding. It demonstrates that high precision magnetic survey and 210 Po method can effec- tively infer structure, faults distribution which provides a favorable exploration area range and a reliable geophysical basis for the next census.
