Celestine is closely associated with anhydrite (CaSO4) and sulphides; 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.
