Abstract The Maršíkov–Schinderhübel III pegmatite in the Hrubý Jeseník Mountains, Silesian Domain, Czech Republic, is a classic example of chrysoberyl-bearing LCT granitic beryl–columbite subtype. This thin dyke, (up to 1 m thickness biotite–amphibole gneiss characterised by symmetrical internal zoning. Tabular and prismatic chrysoberyl crystals (≤3 cm) occur typically intermediate albite-rich ...

Abstract The paragenesis and composition of bavenite–bohseite were investigated in fifteen granitic pegmatites from the Bohemian Massif, Czech Republic. Three types distinct their relation to primary Be precursors, mineral assemblages, morphology origin recognised: (1) hydrothermal crystallised miarolitic pockets residual pegmatite fluids; secondary two types: (2) a proximal type restricted spa...
