The ore-forming fluid distribution and evolution of interstratified skarn copper-gold deposits in Shizishan ore-field of Tongling, Anhui Province

摘要

The studies on mineral inclusions have revealed that the ore-forming fluid distributed regularities in space and evolution consistently in time for the interstratified skarn copper-gold deposits in Shizishan ore-field of Tongling.Particularly, the migration of the ore- forming fluids is in the condition of "equal temperature field" in different mineralization stages. The mixing and evolution of two end-members fluids at least occur in mineralization process but mainly magmatic hydrothermal solution. All of the stratified skarn deposits were controlled by universal tectonicmagma activities.
