地球化学异常的查证方法及效果

异常查证是检验地球化学勘查的试金石。目前在异常查证中，存在依赖肉眼观察作为肯定或否定异常的准则；没有把握全局，过早地把重点放在局部地段等问题。在异常查证中严格执行三级不同查证方法和要求，才能取得像岩背锡矿、金家坞金矿的查证效果。

Determination Methods and Effect for Geochemical Anomaly

Anomaly investigation and verification is a touchstone in examining the exploration of geochemistry. In the current course of investigation and verification, determination with naked eyes are considered as a rule, absence of overall understanding and the focus is put in the local blocks prematurely have been the subjects. It is concluded that three levels of different methods and requirements shall be strictly implemented so as to acquire the results like tin deposit in Yanbei and gold deposit in Jinjiawu.
