摘要
天然大地电磁法由于其装备轻便、受地形影响较小,在高原、山区的找矿工作中能够体现出优越性。在四川宁南铅锌矿区的找矿工作中,实施了4条天然大地电磁锁频测深剖面,取得了11个卡尼亚视电阻率异常。现场地质调查证实,除少数非矿致异常外,多数异常与出露矿体的位置和产状及地质认识基本吻合,取得了较好的找矿效果。
natural magnetotelluric method is superior over others in ore exploration at plateau and mountainous areas due to its simple and easily movable equipment and less influence from topography. During exploration of Paoma Pb-Zn deposit, Ningnan county, Sichuan province 4 locked-frequency- natural magnetotelluric sounding sections were measured and 11 apparent resistivity anomalies were detected. The field check up proves coincidence of the anomalies with position, occurrences and geological interpretation of the exposed ore bodies. The result is good.
