Abstract: Hewa gold deposit is located in the gold metallogenic belt in the eastern North China Craton. There are several gold mineralized belts on the surface, with the precondition for the development of gold deposit. Although a lot of exploration research work has been done, the geological understanding of this area is still limited due to lack of effective deep exploration means. Based on previous geological research, combined with wide field electromagnetic method and deep drilling results, this paper summarizes the stratigraphic geological characteristics of Yongning basin, comprehensively analyzes the metallogenic materials at different depths, and forms a new understanding of metallogenic characteristics and model of Hewa gold deposit. It is considered that the tensile fractures developed in and near the contact interface between Yongning Formation and underlying gneiss at a depth about 1 000 m, and even all the locations of hydrothermal activity are favorable for mineralization. According to the existing scale of gold mineralization, it is inferred that there is a good gold metallogenic prospect in the study area.
