摘要
本次研究使用河北省新一轮的1∶2.5万高精度航空磁测资料,通过对航磁数据进行化极、垂向一阶导数、垂向二阶导数等一系列处理后,对河北省阜平县某半隐伏岩体进行岩体圈定、岩性划分,表明了大比例尺高精度航空磁测不但在寻找铁矿上有很大作用,而且在圈定岩体、划分岩性、推断构造上也有显著的效果,尤其在推断隐伏岩体和构造方面,给基础地质的研究提供了很大帮助。
This paper uses a new set of 1∶25,000 high-precision aeromagnetic survey data in Hebei province to delineate and lithologically divide a semi-concealed rock mass in Fuping county,Hebei province after a series of processing of aeromagnetic data such as polarization,vertical first derivative and vertical second derivative.It is shown that large-scale high-precision aeromagnetic survey is not only very useful in finding iron ore,but also has significant effects in delineating rock mass,dividing lithology and inferring structure,especially in inferring concealed rock mass and structure,which is of great help to basic geological research.
