Coupled with the progress of science and technology and the level of technology to improve the smelting, easy to find type simple reserves are relatively concentrated, iron is almost used up, and in recent years with the international market, the rising price of steel, iron ore exploration has become the hot metal exploration. 山东马戈庄地区为大片第四系覆盖，基岩出露较少或基岩风化严重，埋藏较深，地下地层构造复杂，岩石结构混杂，为铁矿带的形成提供了前提。 Shandong Ma Ge Zhuang area for large quaternary cover, bedrock exposed less or bedrock weathering serious, deep buried underground strata, complex structure, rock structure of hybrid, provides the premise for the formation of iron belt. 本文在较为详细地阐述高精度磁测的基本理论和基本方法后，重点对马戈庄地区的地质状况进行了调查，进而又以铁矿石和围岩具有明显的磁性差异为基础，根据高精度磁测具有抗干扰能力强及精度较高的特点，推断了马戈庄地区地层的构造和铁成矿带的分布及范围，为今后的铁矿开采提供了依据。 This paper introduces the basic theory of high precision magnetic survey and basic method in detail, especially geology to Margo Zhuang area were investigated, and then to iron ore and rock magnetic differences as the basis, according to the characteristics of high precision magnetic survey has strong ability of anti-jamming and high precision, inferred the distribution and range structure and iron ore formation Margo Zhuang area belt, provide the basis for future iron ore mining.
