Abstract The Dujiahe gold deposit, occurring in the Mesoproterozoic Heilongjiang group, is controlled by antiform structures. Based on detailed field geological survey, the paper studies the geological characteristics, structure and texture of ores and mineralogical characteristics of gold. The results show that the ores are crystalline and idiomorphic granular in textures, with dense massive and disseminated structures. The wall rock alterations include sericitization, silicification and pyritization. The genetic type belongs to ductile-shear-zone-related gold deposit. The prospecting indicators such as strata, structure and alteration are also pointed out, which provides theoretical basis for prospecting in the area.
