Hydroxycalciopyrochlore from regionally metamorphic marble at Bližná , Southwestern Czech Republic
Original language description
We describe an unusual occurrence of hydroxycalciopyrochlore, in carbonatite-like marble exposed in the Václav graphite mine at Bližná, southern Czech Republic. Roundish grains attain up to 3 cm, and euhedral crystals are up to 2 mm across. An empirical formula, calculated on the basis two B atoms per formula unit (pfu), is: (Ca0.52Na0.02Mg0.06Mn0.01Fe0.15Y0.06sigmaREEs0.23Th0.29U0.01)1.36(Nb1.14Ti0.85)2 O6(OH)0.72 .The associated minerals, in addition to the rock-forming minerals calcite, phlogophite and edenite, include ilmenite, magnetite, euxenite, uranoan thorite, rutile, zircon, molybdenite, chalcopyrite, galena, sphalerite,pyrite, pyrrhotite, barite and apatite. This is the first occurrence of a pyrochlore-group mineral in regionally metamorphosed marble. The assemblage is considered to represent a metamorphosed carbonate-dominant sediment containing evaporitic horizons and volcanic detritus.
