Abstract

V originále

Syn-tectonic quartz-calcite veins containing blue beryl are enclosed in hematite>magnetite-rich portions of the low-grade metamorphosed Fe-deposit Skály near Rýmařov, Czech Republic. Aggregates of pale to deep blue beryl, up to 2 cm in diameter, are associated with euclase, clinochlore, hematite, albite and dravite. Complexly zoned beryl crystals consist of skeletal aggregates of beryl I randomly distributed within volumetrically dominant beryl II with narrow rims of beryl III. All types of beryl have similar contents of Na (0.32-0.49 apfu) and Mg (0.31-0.41 apfu) but variable contents of Fetot (0.05-0.34 apfu) and Al (1.20-1.62 apfu), and elevated contents of Li, up 1314 ppm (0.28 wt.% Li2O) in beryl I.
