摘要:
以宁芜北火山岩覆盖区南门头工区为例,利用地质、物探等综合找矿方法进行深部矿勘查方法技术的探索。通过研究岩石物性特征,综合分析研究区重力、航磁异常、1:10000面积性高精度磁法测量和重力测量、电法(CR 法)综合剖面测量资料,对异常进行综合分析和解释,并对成矿有利部位进行钻探验证,辅以井中物探,取得了较好的应用效果。以南门头工区勘查工作为例,总结了火山岩覆盖区勘查过程中制约找矿的干扰因素,为今后类似覆盖区开展深部找矿工作提供参考。
Abstract:
Taking the Nanmentou work area in the northern Ningwu volcanic covering areas as an ex ‐ample ,this study applied the integrated ore‐prospecting methods of geological and geophysical prospecting to explore the deep ore exploration .In combination with petrophysical characteristics in the studied area , we have conducted comprehensive analyses on and interpretation for the gravity and aeromagnetic anoma‐lies ,1 :10000 high‐precision magnetic and gravity measurements and electric comprehensive profile meas ‐urement .Drilling verification ,supplemented with borehole geophysical prospecting ,has achieved good re‐sults in advantageous positions of mineralization .With a case study in the Nanmentou area ,authors sum‐marized the interference factors restricting ore prospecting in volcanic covering areas ,providing reference for future deep ore‐prospecting in volcanic rock covering areas .
