摘要
随着我国矿产勘查开发力度的不断加强,地表矿、浅部矿、易识别矿日趋减少,矿产勘查工作正朝着寻找隐伏矿、深部矿、难识别矿的方向转变。因此,深部地质勘查研究日趋具有非常重要的意义。在招远市留仙庄矿区利用可控源音频大地电磁测深(CSAMT)及频谱激电测深(SIP)法对深部异常进行查探,共布设2条物探剖面,分别为108号、132号勘探线剖面。通过CSAMT与SIP测量工作,大致确定了招平断裂带的产状,对2条剖面CSAMT测量结果对比,大致确定了2条剖面所测区域在招平断裂带沿产状向下延伸位置及对应关系,圈定了3处高极化异常区域。该次工作充分发挥物探优势,验证了物探方法在深部找矿勘查中的有效性,总结了存在的问题,为下一步地质勘查工作提供可靠依据。
Accompanying with continuous development ol mineral exploration in our country, surface mine, shallow mine, and easy to identify minerals are decreasing. Exploration ol mineral resources is changing to search lo r hidden ore, deep or and dif f icult to identify ores. Therefore, the study on deep geological exploration is of great signifi-cance. By using controlled source audio frequency magnetotelluric sounding （ CSAMT） and spectrum sounding （SIP） method, deep anomalies in Liuxianzhuang area of Zhaoyuan city have been explored Two geophysical pro-files have been laid respectively, they are No.108 and No.132 exploration line profiles. Through CSAMT and SIP measurements, the occurrence of Zhaoyuan-Pingdu fault belt has been determined roughly. Comparing CSAMT measurement results of two profiles, position and the corresponding relationship between the two profiles in the re-gion of Zhaoyuan-Pingdu fault along the occurrence and downward have been generally identified. Three high polar-ization anomaly areas have been circled. In this work, the advantages of geophysical exploration have been played well. The effectiveness of geophysical prospecting methods in deep prospecting has been ve r ifie d, existing problems have been summarized, and a reliable basis for the next step of geological exploration has been put forward.
