分析了多因复成矿床磁性体的典型特征,总结了该类型矿区磁异常反演解释存在的主要问题,通过提取磁异常基本特征、引入解释偏角和剖面位移等概念,提出了以磁异常共轭解释法为基础的偏位解释法,模型试算及实例分析表明该方法能获得较高的反演精度和符合实际的反演结果,能实现复杂磁异常的反演解释.对比分析认为该方法相对传统方法在一些特殊情况下具有明显优势,是磁法勘探领域中一种新的反演方法,能较好解决多生产实际中一些以往不能解决的重要问题.
This paper analyzes the typical features of magnetism in multi - factor complex deposits and summarizes the main problems existing in the interpretation of magnetic anomaly in this type of mine. By extracting the basic features of magnetic anomalies and introducing the concepts of interpretation declination and section displacement, Conjugate interpretation method based on the bias interpretation method, the model trial calculations and case studies show that the method can obtain higher inversion accuracy and the actual inversion results, to achieve complex magnetic anomaly inversion interpretation.Comparison analysis that Compared with the traditional method, this method has obvious advantages in some special cases and is a new inversion method in the field of magnetic prospecting. It can solve some important problems that can not be solved in the multi-production practice.
