Abstract: The electric conductivity is a relative ruler to the conductance of ore-forming solution.The value of electric conductivity can directly reflect the concentration value of ore-forming solution.Study on fluid inclusion suggests that the high concentrated areas of ore-forming solution are generally where the main(rich)orebodies occur.By replacing concentrated field with electric conductivity field,and setting up a quantitative relation between electric conductivity parameter and orebodies,the electric conductivity of ore forming solution can be used to reflect the rich or poor levels of orebodies,to distinguish the industrial and non industrial veins,to indicate prospecting areas and so on.Another new method in mineral searching is through the pyroelectricity of metallic and semiconductor minerals.In dissimilar miner alizing conditions and forming sections,the values of mineral pyroelectricity and types of thermal conductivity are different.Mineral pyroelectricity can be used to judge the denuding levels of deposits and to assess the mineralized district.In Xijinuoshan ore field,the new techniques and methods of electric conductivity and mineral pyroelectricity are adopted to locate the best mineralization section.The study results show that the mineralized center is not between the exploration lines 440 and 500 where a lot of workload has been put in.The mineralized center of Xijinuoshan reconnaissance area should be situated from exploration line 500 to the granite porphyty body in the east.
