In this paper, geoelectrochemistry was used to carry out feasibility study above nickel deposits in Hejiaya area, Lueyang, Shaanxi Province. The results were compared with results obtained by traditional soil geochemical measurement methods. The results show that geoelectrochemistry and soil geochemical measurements above nickel deposit profiles show anomalies, but the soil geochemical anomalies are not good in content and morphology. It is inferred that the topography and epigenesis may influence the distribution of anomalies, which makes the distribution of anomalies slightly disordered and the clarity of anomalies reduced. Compared with soil geochemical anomalies, geoelectrochemical anomalies show a good correspondence above the ore site, and the anomalies show a steep double-peak or three-peak pattern. In order to further study the distribution characteristics of anomalies on the plane, the authors analyzed the element content of the two methods. It is found that geoelectrochemical method can strengthen anomalies to a certain extent, magnify the anomaly effect and easily summarize the law of element dispersion and enrichment. On such a basis and in combination with the results of geological and geophysical exploration, two favorable prospecting targets were delineated by geoelectrochemistry in the study area, which indicate the existence of concealed orebodies in its deep part, but this conclusion needs to be verified by engineering.
