传统化探方法可能漏掉强度不大但可能致矿的异常,而子区中位数衬值滤波法可以有效地避免地质背景对异常圈定的影响,解决了低背景区和高背景区弱小异常的识别问题,消除了全区统一划分异常下限对化探异常识别的影响。采用该方法在江西某地区发现了多个新的化探铀异常区,并在其中的一些异常区内发现了铀矿点,显示出较好的应用效果。 更多还原

【Abstract】 Traditional geochemical processing method sometimes maybe loses some weak anomalies related to mineralization,the authors can avoid the influence of geology background and can solve the problem of recognizing weak anomalies in the low-background and high-background area with the subinterval area median contrast filtering method.In an area of Jiangxi Province,several new anomalies are identified by this method and uranium mineralized prospects are found among them. 更多还原
