Abstract
EH-4 continuous conductivity imaging technology was employed in search for concealed orebodies so as to achieve a break-through in the Xiangutai ore deposit. The prospecting for copper-polymetallic deposits was preceded by the search for porphyry con-cealed rock masses. It was found that the granodiorite porphyry has three kinds of anomaly marks in the resistivity reversion sectional drawaing:in the transitional zone from high resistance to low resistance, there appear contorted deformation segment, localized high re-sistance segment in low resistance area and localized low resistance segment in high resistance area. Anomaly interpretation and drilling verification were conducted along three typical profiles, with fairly good geological results achieved. The results show that the applica-tion of EH-4 continuous conductivity profile measurements to the ore district has obtained a wealth of abnormal information, achieved good geological effect, and provided geophysical basis in search for porphyry copper polymetallic ore deposits.
