地电化学勘查方法的现状与前景

THE CURRENT AND FUTURE SITUATION OF CHIM ELECTROGEOCHEMICAL METHOD

对地电化学勘查方法的现状和前景作了评述，并提出了我国地电化学勘查方法的发展战略。

The conventional surface geochemical technique, such as soil and stream sediment geochemical surveying, is difficult to be used in the exploration of mineral deposits covered with a thick overburden layer. In order to solve this problem,a number of phase geochemical (partial extraction) method have been developed for the past decades. Therefore, the detection of buried depositis can be made by tracing their secondary epigenetic haloes in the earth’s surface. The CHIM electrogeochemical method can be used to promote the movement of cations within the artificial electrical field towards the cathodes, resulting in the concentration of the cations in the cathodes.In this way,the concentration of the cations in the cathode can be determined for the purpose of the prediction of mineral resources. The current and future situation on the CHIM electrogeochemical method are discussed and its development strategy in China is also presented in this paper.
