Sr-sulphate and associated minerals found from kyanite-bearing eclogite in the Moldanubian Zone of the Bohemian Massif, Czech Republic

Popis výsledku v původním jazyce

Sr-bearing phase, celestine (SrSO4), was found in ultrahigh-pressure (UHP) eclogite associated with the Nové Dvory peridotite mass in the Moldanubian Zone of the Bohemian Massif, Czech Republic. Celestine is closely associated with anhydrite (CaSO4) andsulphides; pyrite, pyrrhotite and chalcopyrite. Fe-rich unknown silicate mineral developing along the margin of the sulphide minerals was also found. Those minerals in the eclogite occur in the matrix that is mainly occupied with fine-grained clinopyroxene aggregate. A common Sr reservoir in eclogite is known to be epidote, but the maximum pressure-temperature (P-T) conditions of the studied eclogite was estimated as about 1000?1100°C, 4.5?4.9 GPa. In such extremely high P-T conditions, epidote should be unstable. In fact, epidote is absent from most of eclogites in the Moldanubian Zone of Czech Republic.
