摘要
对磁性体的不同研究方法做出了总结,对航磁数据的几种处理方法进行了简单介绍,便于根据实际情况选择最能突出磁异常的平面形态的处理方法,定性分析对磁性体做出推断。然后对切线法,欧拉法,磁化强度成像方法,功率谱法这四种定量解释磁性体的埋深以及边界的方法进行了综合研究。通过分析磁异常与场源的对应关系,从而研究磁性体与成矿关系。根据不同产状磁性体磁异常特征能够准确、快速、及时地做出正确结论。实现在中深部找矿中的重要指导作用,为地质勘查提供依据。
This paper summarizes the different research methods of magnetic bodies,and introduces several methods for processing aeromagnetic data.It is convenient to select the processing method that best highlights the magnetic anomaly according to the actual situation.The analysis makes inferences about the magnetic body.Then,thetangent method,the Euler deconvolution method,the magnetization imaging method,and the power spectrum method are used to comprehensively study the methods of quantitatively explaining the buried depth and boundary of the magnetic body.By analyzing the correspondence between magnetic anomalies and field sources,the relationship between magnetic bodies and mineralization is studied.According to the magnetic anomaly characteristics of different magnetic properties,the correct conclusion can be made accurately,quickly and timely.It realizes an important guiding role in prospecting in the middle and deep parts and provides a basis for geological exploration.
