安徽铜陵大涝地区综合物探勘查多金属矿应用效果

Effect of multiple geophysical methods applied in polymetallic ore deposits in the Dalao area, Tongling, Anhui

结合已知地质成矿规律,通过地面高精度磁测工作查明勘查区范围内的隐伏性岩体的分布;通过大功率激电中梯扫面和激电测深查明勘查区范围内与成矿有关的金属硫化物的分布及向下延伸状况,确定埋藏深度不大;通过磁法、激电中梯、激电测深工作,几处异常都呈现相对高磁-高极化率的反映,推断有成矿的可能,建议在加强地质论证的基础上实施钻孔验证工作。

Based on the known geological and metallogenic regularity, the distribution of concealed rock masses in the work area was determined by high-precision magnetic surveying on the ground. The distribution and downward extension of metal sulfides related to mineralization in the work area were found by high-power IP intermediate gradient method scanning and IP sounding, and the burial depth was found small. Through magnetic method, IP intermediate gradient method and IP sounding,several anomalies show relatively high magnetism and high polarizability, and are thought to be related to mineralization. A drilling test was suggested after strengthened geological demonstration.
