Isotopic indication to source of ore materials and fluids of the Wangfeng gold deposit in Tianshan: A case study of metallogenesis during collisionalorogenesis

The Wangfeng gold deposit is one of the five most important gold deposits i n the Tianshan. Studies of its metallogenic time, space, geodynamic backgro und, ore feature and ore fluid have proved that the deposit formed in the l ate Paleozoic continental collision, and consequently is a suitable delegat e to probe mineralizing regularities during collisional orogenesis. Isotopi c studies including O, D, C, S, Pb and Sr reveal ore materials derived from sedimentary association (including carbonate and sulfate), which further r efers to the Hercynian carbonate-silicolite-argillite-formation north to Wa ngfeng camp. At the end of Paleozoic, the southward intracontinental subduc tion of Hercynian synthem along the Hongwuyueqiao fault down to the Central Tianshan terrane induced large-scare fluidization which extracted and out- transported ore materials from Hercynian synthem upto shallow fair position s, and finally resulted in the formation of the Wangfeng deposit. This stud y excludes the possibility of other tectonic metallogenic models other than the tectonic model for collisional metallogenesis, petrogenesis and fluidi zation.
