【摘要】：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.
[Abstract]:This paper analyzes the typical characteristics of magnetic bodies in polygenetic complex deposits, summarizes the main problems existing in the inversion interpretation of magnetic anomalies in this type of mining area, and introduces the concepts of interpretation angle and profile displacement by extracting the basic characteristics of magnetic anomalies. A skew interpretation method based on conjugate interpretation method of magnetic anomalies is proposed. The model trial calculation and example analysis show that the method can obtain high inversion accuracy and practical inversion results. The inversion interpretation of complex magnetic anomalies can be realized. It is considered that this method is a new inversion method in the field of magnetic exploration because of its obvious advantages over the traditional methods in some special cases. It can solve some important problems which can not be solved in the practice of multi-production.
