The barite and anhydrite inclusions in zircon of gneisses from ultra-high pressure metamorphic zone of the Dabie Mountains and their implications.
大别山超高压变质带片麻岩锆石中重晶石和硬石膏包裹体及其意义

Barite and anhydrite are identified as inclusions in zircon of gneiss from ultra high pressure zone of the Dabie Mountains by using laser Raman spectrometer, and they coexist with inclusion coesite. The discoveries imply that there were metamorphic fluids during the ultra high pressure metamorphic process.
