摘要
冀北地区1∶5万水系沉积物测量圈定的大量地球化学异常,大部分为低缓异常或单元素异常。在"高、大、全"异常区发现了丰宁银矿等一批大、中型矿床,同样在低缓异常区也发现了万全寺、茶棚等中小型矿床,证明有利的构造部位和火山—侵入活动区的低缓异常,也具有很好的找矿指示意义。
Numerous geochemical anomalies delineated by 150 000 drainage sediment survey in northern Hebei are weak and gentle anomalies or singleelement anomalies. In the 'high, large and comprehensive' anomaly areas,a bunch of largeand mediumsize deposits such as the Fengning silver deposit have been discovered, and in the low anomaly areas,some medium and smallsize deposits such as the Wanquansi deposit and the Chapeng deposit have also been detected,which proves that low anomalies at favorable structure positions and volcanicintrusive areas also have good indicating significance.
