Název v původním jazyce

Mineralogy of dumortierite-bearing abyssal pegmatites at Starkoč and Běstvina, Kutná Hora Crystalline Complex

Popis výsledku v původním jazyce

Abyssal pegmatites from Starkoč and Běstvina are typical examples of the AB-BBe subclass pegmatites in the Bohemian Massif. The features typical for origin and evolution of both abyssal pegmatites are better preserved in the pegmatite at Starkoč, where,based on paragenetic relationships, three distinct assemblages were recognized. Plagioclase, quartz and muscovite are major minerals in the pegmatite veinlet; the most common accessory minerals include tourmaline, dumortierite, garnet, K-feldspar and kyanite, whereas only trace amounts of chrysoberyl, staurolite and several very rare accessory minerals were found. Composition of tourmaline is controlled by the two-stage evolution of the pegmatite. Strakoč and all other known pegmatites of AB-BBe subclass in the Bohemian Massif occur in the Gföhl Unit, along the easternmost border of the Moldanubicum. Pegmatite host rocks exhibit HP metamorphic conditions and low degree of MP overprint.
