摘　　要：在柳河马家店铁矿中应用高精度磁法勘探,证明了磁法在寻找磁铁矿上具有显著的效果。文章通过论述磁异常特征,结合本区的地质情况,对所取得的磁异常进行定性研究,同时结合基础地质工作,在磁异常上实施工程验证,成功发现铁矿床,总结该区铁矿成矿规律,为今后物探、地质相结合的综合找矿起到了一定的指导作用。Applying the high precision magnetic prospecting to Majiadian iron ore, we proved that the magnetic method has significant effect in searching magnetite. In the article, the authors discusse the features of magnetic anomalies, combining with local geological situation, did qualitative research on the magnetic anomalies. Meanwhile, combining with the basic geological work carry out project veriifcation in the magnetic anomaly, and discover iron ore deposits. Regularities of ore formation in this area are summarized, which plays a guide role for geophysical and geological integrated prospecting in the future.
