摘要
The Baoxinggou gold deposit is located in the northeast of Tahe County, Heilongjiang Province. Two ore bodies are found in the continental clastic rocks and altered diorites and dikes of dioritic porphyrite of Jurassic Emurhe and Ershierzhan formations. The ores are mainly altered sandstone and fractured alteration rock types. Based on the field survey and research on the ore-forming conditions of Baoxinggou gold deposit, this paper concludes that the Late Yanshanian magmatism activated and emigrated the Au element in the wallrock. The gold deposit is formed in the contact zone between dikes and clastic rocks and in the fracture zone. The Late Yanshanian magmatism provided space, heat and fluid, as well as ore-forming matters for the gold deposit.
