众所周知,寻找大而浅的硫化物金属矿床,用常规物化探方法就可以获得比较清晰的异常,而且辨认矿与非矿异常比较容易,因此,物化探普查的地质效果和经济效益是比较显著的。然而,目前物化探面临的主要任务是寻找埋藏较深的盲矿体。在新的情况下,如何提高物化探的找矿效果和经济效益,是物化探找矿工作急待解决的问题。本文试图通过湘南热液铅锌硫化矿床物化探找矿效果的总结研究,对寻找深部盲矿体和识别电法矿异常与非矿异常两个问题进行探讨。
As we all know, looking for large and shallow sulfide metal deposits, using conventional geophysical and geochemical methods can get more clear anomalies, and identification of ore and non-mine anomalies easier, so geophysical and physical survey of the geological and economic benefits are more significant . However, the main task now facing geophysical prospecting is to find buried deep blind ore bodies. In the new situation, how to improve the prospecting and geophysical and geochemical exploration results and economic benefits is the geophysical and geochemical prospecting work to be solved. This paper attempts to summarize the prospecting results of the geochemical prospecting of the hydrothermal Pb-Zn sulphide ore deposits in the southern Hunan province, and discuss the problems of searching for the deep blind orebodies and identifying the abnormalities and non-mine abnormalities of the electrophorous ore.
