摘要
地面高精度磁测能够可靠地反映控矿地质体的磁性变化,了解隐伏的控矿岩体、构造和含矿蚀变破碎带的分布。利用地面高精度磁测在磐石市胜利屯钼矿区进行扫面测量,实测面积11.56 km2,测点5777个,圈定出7个高磁异常带。进而在重点区段实施初步工程验证,见矿率高,从而说明了地面高精度磁法测量找寻钼矿的可行性和有效性。该区具有较好的找矿前景。
The method of high accuracy magnetic can indicate the magnetic change of geological body which controls the gold mine, the distribution of rock bodies, structures and altered fracture zone .By using the method of high accuracy magnetic prospecting on earth surface to measure all the gold zone in Shenglitun molybdenum deposit of Panshi City, the survey involving 11.56 km2 with 5777 easuring points was carried out, and three high magnetic anomalies were defined. The preliminary test at the key site shows the feasibility and efficiency of the high-precision ground magnetic method in searching magnetite.It indicates there is great potential for discovering the large-sized molybdenum polymetallic deposit in the prospectmg area.
