|Summary:||Hedong gold deposit is located in the middle of Wangershan fault.The depth of prospecting in the deposit had exceeded 800 m. The ore exploration scheme based on multiple abnormal information was established according to the intense disturbance condition and the demand of exploring depth of 2000m. The method of tectonic geochemistry was chosen as the geochemical method. The remote sensing alteration information was from ETM multispectral data of Landsat 7of USA. Wide field electromagnetic sounding methods was chosen as the geophysical prospecting method and 9survey lines were completed according to 120m×50m survey grid. Two prospecting targets were delineated according to the abnormity of remote sensing pelitization alteration and the tectonic geochemistry of Au, As and Cu in the plane and the low resistivity abnormity from wide field electromagnetic sounding methods in the section. New gold orebodies were discovered at the depth from 300m to 1300mby drillings.|
