Abstract: The detecting depth of geo-electrochemical extraction method is large,it has the ability to determine a single detection target,it is suitable for the Quaternary system coverage.The anomalies can be found effectively under the conditions of the unsatisfactory effects obtained by the conventional geophysical and geochemical prospecting methods,so the geological conditions of the detection region can be detected rapidly,effectively and accurately.Firstly,the feasibility test in the Qinlinchang mining area with the known engineering controlling ore-bodies is done,then,the geo-electrochemical extraction method is used to conduct the prospecting prediction of concealed Pb-Zn deposit in the unknown mining area.The application results show that the abnormal points of the two section lines of the unknown mining area are consistent with the geological prospecting information,the ideal prospecting effects of the geo-electrochemical extraction method is obtained.

Key words: Geo-electrochemical extraction method, Carbonate rock area, Concealed Pb-Zn deposit, Prospecting prediction
