| 摘 要： | 随着地表矿日趋减少,可供查证的"高、大、全"异常越来越少,找矿重点也由找地表露头矿向半隐伏矿、隐伏矿的方向转移.因此,弱小异常的识别就显得尤为重要.作者尝试地运用子区中位数衬值滤波法(SAMCF)对内蒙古绰源地区1/5万水系沉积物测量成果进行处理,通过与传统方法对比,发现此方法既可突出强异常及压抑背景噪音的影响,又可强...

| Abstract: | With the dwindling of surface minerals.The verifiable anomalies are fewer and fewer,prospecting direction will have to change from surface minerals to the half-buried,buried minerals.Therefore,identification of weak anomaly is particularly important.The authors try to process 1:50 000 stream sediment survey results in the Chuoyuan,Inner Mongolia by the SAMCF.Compared with traditional methods and found this method can show the strong anomalies,reduce the effect of background noise,and strengthen weak anomali... |
