摘要
简述频率域航空电磁测量基本方法原理,讨论解释参量的特性和用于岩性地质组合单元填图的技术,介绍了应用双三频航空电磁资料在推断岩性地质构造方面的地质效果。利用航空电磁勘查资料进行地质填图,可给区域地质调查补充许多以前未发现的地质构造信息,并能增强局部异常对探测目标物的识别能力,提高勘查效果。
Aero-electromagnetic data applied to geological mapping are very important in aero-electromagnetic exploration.These data can not only provide abundant new information of regional geological structure but also improve the exploration effect and raise the recognition capability of anomalies for surveyed objects.At present,the aero-electromagnetic method in China uses three kinds of T-R loop sets.On the basis of their principles,this paper has discussed specialities of the aero-electromagnetic induction secondary field response parameters and their conversion parameters called ＂mapping interpretation parameters＂,and pointed out the existing problems in the aero-electromagnetic survey.The mapping technique for lithologic-geological unit was used in Longmen and Wuda areas,with fairly good results obtained.
