随着物探磁法探寻磁铁矿工作程度的深入,对低缓磁异常和次级磁异常的研究已成为当前磁异常研究工作中的主要任务之一.本文以××铁矿区的8-24勘探线和×××铁矿区为例,总结了这二个矿区次级磁异常的研究经验.着重阐明在次级磁异常推断解释过程中,系统地研究矿石磁参数的特性及变化规律、分析影响矿石磁性的因素、合理地选用矿体的磁化强度矢量的重要意义.它有
With the deepening of geomagnetic exploration of magnetite work, the research on low geomagnetic anomalies and secondary magnetic anomalies has become one of the main tasks in the current study of magnetism anomalies.In this paper, Exploration line and × × × iron ore district as an example to summarize the research experience of the secondary magnetic anomalies in these two mines, and emphatically illustrate the characteristics and changes of the magnetic parameters of the ore systematically studied in the process of extrapolating and explaining the secondary magnetic anomalies, Analysis of the factors that affect the magnetic properties of ore, the rational use of ore body magnetization vector significance. It has
