The Application of High Power IP Survey In Prospecting of Yanggou Gold De-posit,Liaoning Province
The Yanggou gold deposit was located in the northern part of the Paleoproterozoic rift valley bordering the Taizihe-Hunjiang depression belt in eastern Liaoning Province.The old strata in this area were developed and there existed comprehensive geochemical anomalies such as copper,lead and zinc.The prospecting work progresses slowly due to the influence of surface veg-etation.There existed obvious differences in the polarizability and resistivity of rock and ore in the area,and it was feasible to use electrical characteristics to measure high power IP.By carrying out high-power IP measurement work in the region,three low-resistance and high-polarization abnormal regions and one high-resistance and high-polarization abnormal region were delineated.The exploration trough and drilling verification engineering in abnormal area A showed good mineralization information,and one ore body with high ore grade,over 100 m in length and 0.3～0.91 m in width was delineated.High power IP survey could play an important role in delineating favorable ore-forming areas and searching for concealed orebodies in the exploration of Yanggou gold deposit in Liaoning province.
