摘要
The purpose of this work is to develop a set of effective methods to predict mineralization potential at depth. The GDP-32II multi-function electrical measurement system is used to obtain the charging rate of geological bodies at depth. In this system there is a pole-dipole device, and the induced polarization method in the time domain is used. The survey pot space is 40 m, and the longest supply electrode separation is greater than 1 000 m. Using the EH4 conductivity imaging system, electronic resistivity of geological bodies is measured, with electrode spacing 20 m or 40 m. The results show this combined method can measure the charging rate 340 m beneath the ground and electronic resistivity at depth 600 m.
