摘要
Baxiannao is a typical mineralized fractured zone-type W-Sn polymetallic deposit which was discovered recently.Based on detailed petrographic observations and microthermometric studies of fluid inclusion,hydrogen and oxygen isotopes and radiometric dating,this paper studied the origin and evolution of the ore-forming fluid,ages of tungsten mineralization and petrogenesis and tectonic environment of this deposit.Combined with the available from the literature,it can be concluded that tungsten mineralization occurred at the same geodynamic background that is Jurassic intraplate extensional environment during the large-scale extension period of lithosphere in South China.
