Hydroxycalciopyrochlore from a regionally metamorphic marble at Bližná, Southwestern Czech Republic
Original language description
We describe an unusual occurrence of hydroxycalciopyrochlore in 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: (Ca0.48Na0.02Mg0.06Mn0.01Y0.06.SIGMA.REEs0.27Th0.27U0.01).SIGMA.1.12 (Nb1.06Ti0.79Fe0.14W0.01).SIGMA.2 (O4.96OH1.04).SIGMA.6(OH)0.81•H2O. The associated minerals, in addition to the rock-forming minerals calcite, phlogopite 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-dominated sediment containing evaporitic horizons and volcanic detritus. Now give the reader an explanation, what makes it carbonatite-like?
