高精度磁法在江西永吉地区磁铁矿勘查中的应用

Application of High-Precision Magnetic Method to Magnetite Survey in the Yongji Area,Jiangxi

结合江西省永吉地区高精度磁测,对磁异常进行分析,给出地质解释和初步结论,并结合地质资料,查明区域控矿地质条件和构造。运用综合信息进行成矿预测,针对其中一个剖面进行向上延拓推断解释,成矿远景区初步的预测,发现高精度磁测在铁矿勘查中的应用效果是明显的。

With high--precision magnetic survey in Yongji county of Jiangxi province, it gives its geological interpretation and preliminary conclusions by analyzing the magnetic a- nomalies, and then uses the geological data to find out the regional ore--controlling geolog- ical conditions and structure. With the application of integrated information to metallogenic prediction, as one profile for upward continuation deduces the interpretation, the prelimi- nary prediction is made in metallogenic prospective areas. The results show that the high precision magnetic survey is obviously effective in the iron ore exploration.
