Abstract
An extraordinary rich supergene mineral association (about 20 determined mineral species) has been discovered in an active marble quarry Smrčník located at NW slope of the hill Smrčník (799 m a.s.l.), 2 km NW of the village Lipová-Lázně, 7 km WNW of Jeseník, Rychlebské hory Mountains, Czech Republic. The origin of supergene minerals is connected with weathering of primary sulphides (galena, chalcopyrite, sphalerite) in quartz-calcite hydrotermal vein in the conditions of supergene zone in-situ. The most common supergene mineral is cerussite, quite abundant are anglesite, phosphohedyphane, hemimorphite, malachite, chrysocolla, fornacite and vauquelinite. Other determined minerals are rare: aurichalcite, caledonite, cesàrolite, conichalcite, descloizite, duftite, leadhillite, linarite, mottramite, plumbojarosite, rosasite and wulfenite. The detailed descriptions, X-ray powder diffraction data, refined unit-cell parameters and quantitative chemical composition of individual studied mineral phases are presented.
