我国金属矿物探已经过了三十年发展的历程.由于广大物探技术人员的努力,不论是在理论计算还是在野外找矿方面,都取得了很好的成绩,累积了宝贵的经验. 磁法方面的地质效果最明显.五十年代基本上是研究强磁异常.六十年代是研究低缓异常.当时很多铁矿区为了提高精度,都重新系统地扫面积.因为只有磁测精度提高以后才有可能研究低缓异常.低缓异常的概念包括的范围很广,一般是指单个孤立数值为几百伽马的异常,过去一直被忽视.1964年邯郸中关低缓异常见矿以后,大家这才注意.以后研究这类异常发现了不少新矿床,如山东莱芜张家洼异常.另一方面还研究了
China’s metal mineral exploration has gone through 30 years of development.As a result of the efforts of the vast number of geophysical technicians, both in theoretical calculations and in the field to find ore, have achieved good results, accumulated valuable experience .Magnetration The most obvious geological effect in the 1950s is basically the study of ferromagnetic anomaly 60s is the study of slow and anomalous when many iron ore district in order to improve the accuracy of the system to sweep the area again because only improve the accuracy of the magnetic It is possible to study the slow anomaly. The concept of low anomaly includes a wide range, generally refers to a single anomaly of a few hundred gamma was isolated in the past has been neglected .1964 Zhongguancun Low Handicap common mine, we only pay attention After the study of such anomalies found a lot of new deposits, such as Zhangjiawa, Laiwu, Shandong anomaly. On the other hand also studied
