The relationship between gold mineralization, high K calc-alkaline to alkaline volcanic rocks, and A-type granite: Formation of the Daxiyingzi gold deposit in northern North China Craton

•Gold mineralization in the Daxiyingzi ore distract is associated with quartz veins hosted by volcanic rocks.•Fluid inclusion and stable isotope data suggest magmatic origin of the mineralizing fluids.•The mineralization is classified as epithermal-mesothermal gold deposit.•The gold mineralization took place during 149–158 Ma.
