Abstract:

内蒙古羊蹄子山-磨石山钛矿床是近几年国内所发现的新型钛矿床,其中,羊蹄子山矿带为热液改造型富钛矿床,磨石山矿带为沉积变质型富钛矿床。这2个矿带的主要有用矿物为锐钛矿、金红石及钛铁矿。根据大量物性测量和研究对比,发现富钛矿石具有较高的密度、弱磁性、高极化率、较低电阻率的物性特征。通过重、磁探测发现了多处有意义的异常,对部分异常进行了钻探验证,结果表明,高精度重力测量是有效的找矿方法,高精度磁法为基本的找矿方法。文章结合该区岩(矿)石的物性特征,探讨了大功率激电和频率域电磁法寻找此类矿床的有效性和可行性。并据此指出,重力与磁法面积测量相结合,在重点地段进行激电与电磁测深,是寻找同类矿床的有效的物探技术方法组合。
