地面高精度磁测在交点型铀矿勘探中的应用
THE APPLICATION OF GROUND HIGH-PRECISION MAGNETIC SURVEY TO THE EXPLORATION OF INTERSECTION-TYPE URANIUM DEPOSITS
摘要
Abstract
The study area is located in the Xiazhuang uranium orefield. The intersection-type high-grade uranium deposits are controlled by tracks of intersection faults and lithology of diabase dykes. The task of this study was focused on finding the concealed diabase dykes. This is because uranium is a non-magnetic mineral, but diabase dykes have strong magnetization. Ground high-precision magnetic data show that the amplitude of the anomalies is between plus-minus dozens of nanotesla. The position of diabase is difficult to judge by planar contours of total-field anomaly, but it well corresponds to the positive value of the 0 degree horizontal first derivative.关键词
