Research on Geophysical and Geochemical Exploration for Prospecting Copper-Nickel Sulphide Deposits in South Jinchuan,Gansu Province

Nickel resource is of great importance in the sustainable development of national economy.This paper conducts a predicting research on seeking the potential Nickel Ores in the southern area of Jinchuan through the combination of methods such as High Accuracy Magnetic Prospecting,TEM,CHIM and the method of measuring the adsorbed mercury in the surface soil,with the aim to alleviate the situation of extremely scarce resources in our country and to lower the risks of exploration.The combined methods are applied into this area,and provide instructions on the identification,buried depth and characteristics of hidden rocks.Besides,it indicates the CHIM method has a better effect in identifying the ore body among the cover regions of dry rock waste.
