Aims of this project are: 1. to bring together people dealing with fractionated granites and pegmatites through the Czech geological institutes and to bring different technologies of melt inclusions (MI) study in routine use in Czech geological institutes. 2. to realise detail study of MI in quartz from subsequent evolutionary stages from three typical, geologically well documented magmatic systems in the Bohemian Massif: highly peraluminous tin-bearing granite, mildly peraluminous subvolcanic granite, and a complex pegmatite. Study of MI from early to late quartz generations enables to interpret the enrichment/depletion of water and volatiles in melt during complex history of evolution of granite system. Comparison of both shallow–seated granite systems with relatively deep-seated pegmatite may demonstrate influence of pressure on the fractionation of evolved granitic melt.
