摘要
沽源-宝昌盆地是一个重要的铀成矿远景区。为在盆地中发现更多的铀矿床,作者在已知铀矿床(点)及其外围进行了系统的岩、矿石物性测定,做了大比例尺高精度磁测及磁电阻率、磁激发极化法、甚低频法、地面γ能谱法测量,得出了具有代表性的地球物理模式。在实际工作中以模式为判据,对已知矿床外围的一些远景地段,应用磁测、甚低频法及地面γ能谱法得到的成果进行了推断解释,指出了矿化远景地段。
Guyuan-Baochang Basin, containing No.1, No .2 U-deposits and No.3prospect, is the main U-deposit prospect region in the western Yanliaomineralization zone. In order to find more U-deposits on and around theknown deposits (prospects) in the Basin, the systematic survey of physicalproperties of rocks and ore, high-sensitive magnetic prospecting, MMR,MIP, VLF and ground gamma-sepctrometry have been carried out on alarge scale, and a representative geophysial model is obtained. Accordingto the model, some U-mineralization prospect areas are pointed out bymagnetic survey, VLF and ground Y spectrometry.
