摘要
介绍了国内外物探技术在区域地质调查中的应用现状,航空物探技术在1∶25万北京市幅区域地质调查中的应用,认为航空物探方法在火山岩、侵入岩和变质岩的岩性填图,以及划分断裂构造和圈定火山机构等方面具有重要作用,特别是在挖掘地下隐伏信息方面的作用尤为明显,能提高区域地质调查的高科技含量与效率。
This paper describes the present situation of applying aerogeophysical techniques to 1 ： 250 000 regional geological mapping. It is believed that aerogeophysical techniques are important in identifying volcanic rocks, intrusive rocks, metamorphic rocks, fractures and volcanic structures, and that the application results are especially obvious in detecting underground information. Therefore, these techniques can make regional geological mapping more effective and scientific.
