The mineral parageneses of the Dolní Bory-Hatě pegmatite dykes, western Moravia, Czechoslovakia
The Dolní Bory-Hatě pegmatite dykes are situated in the Moldanubian complex of the Bohemian Massif, 55 km northwest of Brno, 135 km southeast of Prague. They were being for feldspar minerals. The pegmatite dykes, located in a granulite massif show a concentric zoning, 4 zones are present (in the sequence of formation): granitic border zone (1) with characteristic assemblage of oligoclase + orthoclase + quartz (+ biotite + muscovite); graphic zone (2), K-feldspar + quartz, (albite + quartz); central blocky zone (3), orthoclase-perthite + quartz; albite zone (4). Most of the accessory minerals are concentrated in the albite zone.
81 minerals were found in these pegmatites to date. Their morphology, chemical analyses, and other data are given.
