| Abstract: | The Jinjiazhuang gold deposit exists in the Zhangjiakou gold mineralized area of northwest Hebei.The ore bodies mostly occur in Xiaozhangjiakou ultrabasic rocks mainly consisting of diopsidite.Electron microprobe analysis indicated that it is characterized by the richness of platinum group elements in metallic minerals such as chalcopyrite,galena,sphalerite and pyrite,and the presence of millerite in the gold ore.Studies on carbon,sulfur and lead isotope show that carbon,sulfur and metallogenic elements chiefly come from the Xiaozhangjiakou ultrabasic rocks.However the ore-fluids were largely heated underground water,supported by the hydrogen and oxyen isotopic evidence. |
