| 中文摘要: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。 |

| Abstract:The Yangtizishan-Moshishan titanium deposit is a new type titanium deposit found in recent years. The Yantizishan ore belt is a hydrothermally-altered rich titanium deposit, whereas the Moshishan ore belt is a metamorphosed sedimentary type rich titanium deposit. Main useful minerals in these two ore belts include anatase, rutile and ilmenite. According to physical properties and contrast studies, the authors have found that titanium ores are characterized by high density, weak magnetism, high polarization and low resistivity. It is held that the high precision gravity exploration is an effective method and the high precision magnetic exploration is a basic method, as is evidenced by results of gravity and magnetic exploration and drill verification. The effectiveness and feasibility of large power IP (Induced Polarization method) and frequency electromagnetism methods are discussed according to physical properties of rocks and ores. It is also pointed out that the effective combinations of geophysical methods are the utilization of gravity method, magnetic method and IP method to conduct area measurement and the employment of IP and electromagnetic sounding in key segments. |
