华北地台北缘某地区深断裂的特征及其与铀矿化关系的探讨

DISCUSSION ON DEEP FAULT FEATURES AND THEIR RELATION WITH URANTUM MINERALIZATION IN A CERTAIN REGION AT THE NORTHERN MARGIN OF NORTH CHINA PLATFORM

近年来随着航空磁测精度的提高,磁场信息量的增加,磁场规律性更为突出。航磁在研究区域深断裂构造的地质效果比较显著,特别是通过对航磁异常进行垂向导数、方向滤波等项数据处理,使航磁异常在断裂上显示更加清晰。本文通过航磁推测深断裂的研究,来探讨其与铀矿化的关系。

In recent years with the raising of precision in aeromagnetic survey and with the in-creasing of information content from the magnetic field, the regularity of the magnetic field ismore striking. The geological effect of aercmagnetic survey on the study of regional deepfault structures is relatively evident, especially the data processing such as vertical deriva-tive and directional filtering are conducted by means of aeromagnetic anomalies which areindicated more clearly on the fiults. On the basis of the research on deep faults inferredby aeromagnetic survey this peper discusses the relation between deep faults and uraniummineralization.
