摘要
ChDivSummary name="EnDivSummary">Hubazhuang gold deposit is a typical pyrite-and polymetallic sulfide-quartz lode deposit in the Muping-Rushan gold belt of Jiaodong Peninsula and gold occurs mainly in pyrite and polymetallic sulfide-quartz vein. Fluid inclusion studies show that in the different altered wall rocks and gold ores of different mineralization stages there are three major types of fluid inclusions: CO2-rich fluid inclusions, CO2-H2O fluid inclusions and aqueous fluid inclusions. Temperature decline and fluid immiscibility are the main reason of the gold precipitation. Rb-Sr isochron of sericite in altered rocks shows that the mineralizing age of Hubazhuang gold deposit is (126.5±5.6) Ma.
