本文在研究我国西北某地区区域γ场中,试图定量化地评价晕圈,运用了晕圈发育度φ、局部异常梯度Ks、异常评价系数K等参数。在分析区域地质和地球物理特征的基础上,阐明主要方法技术,总结了区域γ场分布规律,归纳了呈矿γ场与非矿γ场两大类属的判据,根据铀矿成矿地质条件、矿化、γ场、放射性水化、航放及航磁等特征,建立了区域γ场的评价准则,预测了八个铀成矿远景区,形成了本区铀矿找矿方向应是“三条线”的观点,作为运用地球物理信息进行区域物探研究和成矿远景预测的尝试。
In this paper, we study the γ field in a certain area of northwestern China, try to evaluate the halo quantificationally, and apply the parameters of halo development φ, local anomaly gradient Ks, anomaly evaluation coefficient K and so on. Based on the analysis of regional geophysical and geophysical characteristics, the main method and technique are expounded, the distribution rules of γ field in the area are summarized, and the criteria of the two genera of γ ore and non-ore γ ore are summarized. According to the ore-forming geology Conditions, mineralization, γ-field, radioactive hydration, navigation and aeromagnetic and so on. The evaluation criteria for the γ field are established. Eight uranium metallogenic prospect areas are forecasted, and the prospecting direction of uranium deposits in this area should be “Three lines” point of view, as the use of geophysical information for regional geophysical prospecting and metallogenic prospects of the attempt.
