1∶2.5万沟系次生晕地球化学找矿方法探讨

1:25000 GEOCHEMICAL PROSPECTING BY SECONDARY HALO OF VALLEYS

从系统论的观点出发 ,将 1∶2 .5万沟系次生晕地球化学找矿方法的室内布样、野外采样、室内异常圈定与评价和室外异常查证 4个阶段看作一个有机的整体。在工作中 ,从布样阶段开始直至异常评价结束的每一个阶段都考虑后续的各个阶段可能会出现的问题 ,并采取相应应对措施。从布样到野外异常查证都注意地质信息和化探信息的相结合 ,从而总结出一套简便快捷、行之有效的野外工作方法。经过多年的实践与完善 。

Based on the system theory, it is suggested that four procedures, layout of samples, collection of samples, delineation and evaluation of anomaly and testing of anomaly should be integrated. The potential problems must be taken account at every schedule from layout of samples to evaluation of anomaly; the reasonable countermeasure must be worked out. The geological information and geochemical information should be integrated. In doing so, a set of explicit, effective, quick working ways can be worked out. Many years' practice shows that the method has played an important rule in the fieldwork and be accepted by many geological departments.
