摘要
本文就航空甚低频(VLF)电磁法的测量方式、资料处理和山脊地形异常识别方法作了探讨。提出航空VLF电磁法主要用于地质填图,圈定那些有一定规模但导电性不一定很好的地质构造,如接触带、断层、断裂破碎带、蚀变带等,并在河北和山东等地区的应用中,取得了较好的地质效果。
Abstract
This paper deals with such aspects of the airborne very low frequency (VLF) electromagnetic method as modes of its survey, data processing, and techniques for anomaly recognition in ridge topography. It is pointed out that the airborne VLF electromagnetic method is mainly usable in geological map ping and delineation of some geological structures such as contact zones, fau lts, fractural shattered zones and alteration zones, which are fairly noticeable in size but do not necessarily have very good conductance. Its application in Hebei and Shandong provinces has yielded pretty good geological results.
