To develop an effective method to identify ore-controlling faults, we studied the Jiaojia gold metallogenic belt, a most typical altered tectonite-type gold metallogenic belt in the Jiaodong Peninsula, China, and conducted experiments using the 3D distributed direct current-induced polarization (DC/IP) method. Firstly, we tested the ability of using 3D distributed DC/IP method to identify altered tectonite-type gold ore deposits by 3D synthetic modelling. We then collected real data of the Sizhuang gold deposit using the 3D distributed DC/IP method. The resistivity model obtained of this region is generally consistent with the known geological setting. Moreover, to obtain the information about the southern extension of the Jiaojia gold metallogenic belt, we conducted a 3D distributed DC/IP experiment in the Shijia area in the southern segment of the Jiaojia fault. The southern extension of the Jiaojia fault and tectonic evolution of shallow magma in this region were inferred from the 3D resistivity and chargeability models. Based on all the information above, we concluded that the 3D distributed DC/IP method has the advantages of 3D observations, high spatial resolution and great detection depth and will be one of the most effective methods for detecting altered tectonite-type gold ore deposits.
