中华人民共和国成立已经三十年了.三十年来,冶金地质系统的物探工作有了很大的发展,取得了较好的地质效果.现在,大家普遍认识到,要把地质工作的重点转移到找矿上来,就一定要大力加强物、化探工作.磁法是冶金地质中应用得最广的物探方法之一.本文根据个人的体验,谈谈磁法在寻找及勘探金属矿床中的作用,金属矿区大、中比例尺地质填图时应用磁法的问题及提高磁法的地质效果应作的一些工作等三方面的问题. The People’s Republic of China has been in existence for 30 years. Over the past 30 years, the geophysical work of the metallurgical geological system has been greatly developed and has achieved good geological results. Now it is generally recognized that the focus of geological work should be shifted to Metallurgical geology is one of the most widely used geophysical methods.In this paper, based on personal experience, talk about the role of magnetic method in the search and exploration of metal deposits , Metal mining large and medium-scale geological mapping application of magnetic method and improve the magnetic effect of the geological effects of some of the work to be done and other issues.
