| 摘 要： | 近几年来,随着战略性矿产远景调查项目的开展,地面高精度磁测一直是主要的物探方法之一,为区域地质调查、成(控)矿地质构造研究、矿产资源评价等工作提供了丰富的地球物理场信息,同时,在金属矿产勘查中能依据矿体与围岩的磁性差异、伴生的磁性矿物直接或间接确定矿体,尤其在铁矿勘查中,磁测更是一种直接找矿的不可或缺的方法。本文总结了磁异常的数据整理及数据处理中一些方法在使用中的问题,并尝试针对解释推断结果提出可靠的、较可靠的、可供参考的三级评价要求。

| Abstract: | In recent years,with the strategic mineral resources survey,high-precision ground magnetic survey method has been one off the main geophysical methods,which provides a wealth of geophysical field information in regional geological survey,metallogenic control,geological structural study,mineral resources assessment,etc.Meanwhile,in the metal mineral resources exploration,directly and indirectly determine ore bodies based on the magnetic differences of ore bodies and its surrounding rocks,associated magnetic minerals,particularly in iron ore exploration.The magnetic measurement is a direct exploration,indispensable method.This paper summarizes some problems in the data processing of magnetic anomalies and data processing methods in use and to try to explain the inference results,propose reliable,more reliable,three-level evaluation requirements for reference. |
