摘要
This paper mainly presents applications of high-power IP central gradient array profile,highdensity resistivity method and IP sounding in reconnaissance of a copper-rich polymetallic deposit in Qilian Mountain.Ore body has the abnormality of high polarity and medium high resistivity compared with surrounding rocks.Thus Regional IP central gradient array method is used in detect the scale of ore body,IP sounding in identifying the depth and occurrence,high-density resistivity method in finding out the geological structures.Various data are under comparative analyses and comprehensive interpretations for geological prospecting,which gets satisfactory results.
