| 摘 要： | 描述了1：10000地面高精度磁测方法在某地区磁铁矿中的勘探应用，通过对野外磁测数据的处理，磁异常提取及异常与矿产的关系，同时从对磁测数据的反演中获得了矿体深部的空间特征，初步推断了可能存在的有利成矿地段，并对测区进行了简单的地质解释。后经钻探证实推测结果与实际情况相吻合，证明了高精度磁测在该区寻找磁铁矿具有良好的效果。

| Abstract: | This paper actually describes the application of 1：10000 high--precision magnetic survey method to the area of N in Y province. Through the magnetic survey data process- ing, magnetic anomalies extraction and the relations between minerals and anomalies, and meanwhile, through the inversion of magnetic survey data, we can get the spatial character- istics of the deep orebody to make a preliminary conclusion that there may be an advanta- geous metallogenic area, and afterwards make a further geological explanation of the area. Then it is confirmed by drilling to prove that the result is consistent with the actual situa- tion, which proves the high--precision magnetic survey has a good effect on the search for magnetite in this area. |
