Abstract:With two kinds of glasses used as starting material,systematical experiment study had been carried out on liquid separation of granitic silicate melt containing tungsten and tin under the conditions of 850℃ and 150MPa. The results of the experiments indicated that the quenched product glasses did not contain any newly-formed minerals through observation under microscope(200×) and determination of X-rays diffraction.The final glass of each run consisted of two parts with light and dark color,respectively,which represented two phases of liquid-separated melt.In the quenched glass,the dark part was dominant and took a portion of more than 80%.The data of the compositions for the two portions of glass by determination with electronic probe indicated that the light glass contained relatively much silica and less Fe2O3,FeO,TiO2,MgO and CaO.On the boundary between two phases of glass,there did not exist gradually varying zone of the composition,which indicated that complete liquid separation had taken place
