A Further Understanding on Genesis of Shuangwang Gold Deposit in Shaanxi Province

Through a comprehensive analysis for geological features and geochemistry features of albite breccia of Shuangwang gold deposit,we consider that the albite breccia is a sort of hidden exploding breccia,and the albite slate associated is formed by hydrothermal metasomatic,sodic might be derived from neoproerozoic basement Yaolinghe group of sodium-rich metamorphic volcanic rocks.The fluids of forming albitite is a magmatic fluids riched in sodium and volatile,which is closely related to the syntexis magmatism.The main gold mineralization occurred in the hydrothermal filling metasomatic stage after blasting action.The genetic type of Shuangwang gold deposit is hidden exploding breccia type gold deposit.
