电阻率法以地壳中不同岩、矿石及金属的电阻率差异为物性基础,通过观测、研究人工建立的稳定电流场的地下分布和变化规律以达到找矿、研究地质构造和寻找地下水的一种电法勘探的分支方法。本文应用高密度电阻率法对彭山县引水工程在江口镇岷江河道明代沉银分布进行探测,取得了较好的效果,为该地区文物的进一步发掘保护等提供了地球物理依据。
The resistivity method is based on the difference of resistivity of different rocks, ores and metals in the crust. Based on the observation and study, the underground distribution and variation of artificially established stable current field are studied to find the ore, to study the geological structure and find the groundwater Branch method of electrical prospecting. In this paper, the high density resistivity method was used to detect the distribution of Shen silver in the Pengjiang County water diversion project in Minjiang River of Mingkou in Jiangkou Town. The results have achieved good results and provided geophysical evidence for the further excavation and protection of cultural relics in the area.
