Erdaogou Gold Deposit is located in Jiapigou Gold Field and has good prospecting potential.The gold mineralization types in Erdaogou Gold District are mainly gold-bearing quartz vein type and altered rock type.The silicification and limonitization are closely related to gold mineralization,which is an important indicator for ore prospecting in the district.IP medium gradient survey and soil geochemical survey were carried out for the 3 ore prospecting target areas delineated.Based on the survey results,prospecting projects were arranged at locations with low resistivity and high polarization,concentrated element anomalies,and potentials for ore prospecting.Several ferritization(silicification) alteration zones were discovered and ore prospecting breakthroughs were made.It shows that the multi-source information prospecting method combined with geology,geophysics,geochemistry,and remote sensing is more applicable in the Erdaogou Gold District,which can provide a reference for further exploration of the Jiapigou Gold Field.
