地球物理勘探和地球化学勘探已成为地质普查勘探工作中一个重要手段,其作用日益显著。近年来,用物化探方法的地质效果越来越好,对一般金属矿床地面物探勘探深度已达213.5～305米,航空物探达152.5米。在物探技术发展中有以下几个特点: 1.激发极化法发展突出,且效果显著。此法探测深度比一般电法深,可勘探深度一般为200～300米,在理想条件下可达300～600米。此法不仅可以寻找硫化物矿床,而且在寻找地下水和铝土矿时效果也比较好。
Geophysical exploration and geochemical exploration have become an important tool in geological surveying and exploration work, and their role has become increasingly significant. In recent years, the geophysical effect of geophysical and geochemical methods has become better and better. The depth of geophysical prospecting for general metal deposits has reached 213.5 to 305 meters, and aviation geophysical exploration has reached 152.5 meters. There are the following characteristics in the development of geophysical exploration techniques: 1. The induced polarization method is outstandingly developed and has significant effects. The depth of detection of this method is deeper than the general electrical method, and the depth of exploration can generally be 200 to 300 meters, and can reach 300 to 600 meters under ideal conditions. This method can not only find sulphide deposits, but also has better results in the search for groundwater and bauxite.
