可控源音频大地电磁测量在花岗岩型铀矿勘查中的应用
The applications of CSAMT to the exploration of granite type uranium deposits
摘要
Abstract
The granite type uranium deposit mainly occurs in the interior or at the edge of a rock body. The investigation of the develop⁃mental conditions of a rock body thus has significance for uranium deposit exploration. The controlled source audio frequency magneto⁃telluric ( CSAMT) method and its applications in Weijing area were described in this paper. Based on geological data and rock resistivi⁃ty as well as CSAMT data, the authors found the thickness of the granite rock mass and the deep development of the contact zone be⁃tween the granite and the metamorphic rock, and the good results were verified by drilling. A comprehensive analysis shows that CSAMT method has fairly good resolving power in vertical direction. According to results of CSAMT method, the authors detected the thickness of rock bodies as well as the position and the deep characteristics of structures. In addition, the distribution characteristics of the zones of fractures, fissures and vein bodies were detected too. The CSAMT method is an effective means for uranium deposit explo⁃ration.关键词
