Abstract

Abstract: Most of the ore-bodies in grasslands are covered by the Quaternary sediments. In order to forecast the location of the buried ore-bodies in grasslands, the authors use the geophysical exploration methods of VLF-EM and EH4 conductivity image system. The results of the studies show that VLM-EM and EH4 conductivity image system techniques can define the distinct abnormities caused by the mineralized bodies. These two kinds of abnormities are corresponding. Hence, the integrated application of VLF-EM and EH4 conductivity image system is efficient to forecast the location of the buried ore-bodies in grasslands.

Key words: grassland area, location forecasting of the buried ore-body, VLF-EM, EH4 conductivity image system
