区域地球化学调查中注意弱异常查证—以骆驼河金异常查证为例

作者通过区域地球化学调查 ,查证一处水系沉积物测量地球化学弱异常 ,且证实该异常与矿有关 ,并总结了找矿体会和经验。本文进一步说明了区域地球化学调查中不仅对“高大全”异常要给予重视与查证 ,而且对弱异常也应给予高度重视和查证 ,以提高找矿效果

ATTENTION TO THE WEAK ANOMALY INVESTIGATION IN REGIONAL GEOCHEMICAL SURVEYING ——AS EXEMPLIFIED BY GOLD ANOMALIES IN LUOTUOHE GOLD DEPOSIT

The authors made regionally geochemical investigations to probe into the weak geochemical anomalies in sediments from a drainage system. It has been confirmed that the anomalies are closely related to ore mineralization. Experiences in ore prospecting have been summarized in this paper. It is pointed out that emphasis should be stressed not only on the obvious anomalies, but also on the weak anomalies so as to enhance the effectiveness of ore exploration.
