摘要
可控源音频大地电磁法(CSAMT)具有探测深度大、横向分辨率高、抗干扰能力强的特点,在深部找矿勘探中有着重要的指导意义。肖家营子铜钼矿床是辽西地区一个大型矽卡岩型金属矿床,大部分矿体是隐伏矿体,矿区外围的康杖子区与本区有相似的成矿地质环境,成矿地质条件优越.矿体与围岩电性差异明显,通过应用CSAMT,矿体具有低电阻特点,根据成果推断解释,对深部有利成矿部位进行了钻探验证,取得了理想的探矿效果,在矿区外围取得第二深度空间找矿重大突破。
The controllable source audio frequency magnetotelluric method （CSAMT） shows advantages in available depth, lateral sensitivity, the ability of anti - disturbance. The application of CSAMT has the important implication to prospecting in the depth, and has made the great contribution for our national exploration. Xiaojiayingzi copper molybdenum deposit is a large deposit related to skarns in West of Liaoning province. Most of the orebodies is concealed together, Kangzbangzi area and the home court has the similar mineralization geological environment, the mineralization geological condition is favorate. Ore and rock shows different electric characteristics. Through practical CSAMT application in Kangzhangzi deposit, orebodies show low - resistivity characteristics. According to this result, drilling program has confirmed this result and made remarkable breakups in exploration, which leads the second prospecting breakthrough in depth in the mining area. This work has proved the CSAMT is efficient in prospecting program.
