Abstract:

Guoluolongwa gold deposit is located Wangbaogou Group of the east Kunlun orogenetic belt.It is controlled by a ductile shear zone.Mineralized rocks are chlorite phyllite,siliceous slate,and so on.There are plenty of vein rocks in the metallogenic region.Mineralize type includes quartz vein,altered phyllite,fracture zone,vein-like mass.The ore is low content of sulfide,mineral composition is simple in the ores.The study results of sulphur and lead isotopes show that Guoluolongwa gold deposit is very like the others gold deposit of the east Kunlun minerogenetic region.It is a typical type of orogenic gold deposit.It is related to intermediate -acid magma intruded in Varisian-Indian-China periods and it belongs to medium-temperature hydrothermal type.

Key words: Ductile shear zone, Sulphur and lead isotope, Orogenic gold deposit, Guoluolongwa gold deposit, Qinghai Province
