摘要
可控源音频大地电磁法(CSAMT)是深部隐伏矿勘探工作的重要手段之一。将CSAMT法用于安徽石台县老山矿区铜钨钼金多金属隐伏矿勘察,在深入认识研究矿区的成矿规律和控矿因素的基础上,对该区的CSAMT数据进行了预处理和反演,CSAMT反演结果成功地显示出矿体(脉)水平延伸及向下延深情况,通过研究矿区内的地层、构造与岩体的空间分布规律,寻找出有利的成矿部位,为该区寻找隐伏矿提供了有效的勘探资料。
Controlled source audio frequency magnetotellurics(CSAMT) is one of the key role in exploring deep buried deposits at present.The CSAMT has been used to explore buried copper,tungsten,molybdenum,gold,polymetallic concealed deposit at Shi Tai Lao Shan area.Based on the recognition of metallogenic regularity and ore-controlling factors,CSAMT data has been processed and finished inversion.The inversion result of CSAMT shows level extension and the down situation of ore body(vein) clearly.Structure,stratum and spatial distribution of rock in mining area have been studied and favorable mineralization location has been found out,which have provided effective information of exploration for finding buried ore body.
