Descr. články - journal articles Language English Country Slovak Republic Annotation The Brusno-Brzáčka occurrence (N 48.7698772°; E 19.4128150°) is located near the Brusno village (Slovenské Rudohorie Mts. Veporic Unit). Historically, the mineralization was explored by small-scale mining works located at the contact between the siliciclastic rocks of the Upper Permian and the Lower Triassic age. Paleo-Alpine metamorphic-hydrothermal mineralization is represented by quartz, baryte, or quartz-baryte veins, containing weak ore mineralization. Its succession is as follows: coarse-grained quartz I, pyrite (mineralization period I); baryte (II); tetrahedrite-(Zn), chalcopyrite (III); galena (IV) and quartz II (V). Supergene alteration produced initially covellite and spionkopite in the cementation zone. The oldest minerals in the oxidation zone are goethite, pyromorphite and mimetite. They were succeeded by the crystallization of Ba-rich anglesite, which partly overlaps in time with the precipitation of slightly younger anglesite. The formation of baryte partly overlaps with the deposition of anglesite, but in most cases, it is clearly younger. Bismutite is the youngest supergene mineral. A solid solution of anglesite–baryte with a Ba content from 0.29 apfu up to 0.51 apfu (i.e., Ba-rich anglesite) was identified at the studied site. This mineral phase covers the field of immiscibility of the natural solid solution PbSO4 – BaSO4, but the Ba/Pb ratio practically does not enter the baryte field (Pb-rich baryte).

Západné Karpaty (pohorie) Form. Descr. články - journal articles Language English Country Slovak Republic Annotation The studied mineralization is located on the eastern slopes of Lopejské Čelno valley, south of the Lopej village (cadastral area of Podbrezová village, Central Slovakia). The U occurrence was described and classified as U-Cu stratiform mineralization. The mineralization is located in the Ľubietová Zone of Veporic Unit, and is bound to the arkosic sandstones containing Permian volcanoclastic material. The host rock of mineralization underwent low-grade metamorphism and limonitization. Lens shaped ore bodies are characterized by disseminated pyrite, rutile, chalcopyrite, leucoxene and metatorbernite. Small cavities and cracks in rock are also filled and/or coated by goethite, Mn oxides and malachite. Uranium is irregularly distributed within the host rock and is bound to the U-Ti oxides, brannerite and torbernite/metatorbernite. Brannerite and leucoxenized U-Ti oxides are the only one primary uranium U4+ minerals, for the first time identified in studied occurrence. Brannerite forms clusters of needle-like crystals (up to 100 μm in size). It occurs in close spatial and genetic association with U-Ti oxides, rutile, leucoxene and clay minerals. Chemical composition of brannerite and U-Ti oxides differs in ratio of U/(U + Ti): from 0.22 to 0.29 apfu for brannerite and from 0.09 to 0.22 apfu for U-Ti oxides. Metatorbernite forms light green crystals, typically occurs in small cavities and fractures in rock. It shows an unusual light green luminescence under UV radiation. The average chemical composition of metatorbernite can be expressed by empiric formula (Cu0.75Ba0.06Ca0.03K0.04Al0.02Mg0.01Fe0.01)Σ0.94 (UO2)Σ2.00 (PO4)Σ2.01 (H2O)8. Occasionally torbernite/metatorbernite directly replaces single crystals of apatite. URL Link na plný text Public work category ADN No. of Archival Copy 53479 Catal.org.

Západné Karpaty (pohorie) Form. Descr. články - journal articles Language English Country Slovak Republic Annotation Several occurrences of copper sandstone mineralisation type occur in the Permian volcano-sedimentary sequences of the Northern Gemeric Unit (Spišsko-gemerské Rudohorie Mts.). The object of presented mineralogical research was Cu-(U) mineralisation in the copper sandstones at the Šafárka occurrence, located about 4 km SE of Novoveská Huta (part of Spišská Nová Ves district town). Cu-(U) mineralisation occurs in fine-grained psammites of greenish-grey colour. The surface of the samples is limonitized, with coatings of green Cu and U supergene minerals. The main rock-forming mineral is quartz. Carbonate (probably authigenic), muscovite and fragments of sericite shales or highly altered volcanics are present to a lesser extent. Accessories represent K-feldspar, tourmaline and leucoxenized Fe-Ti oxides. Rock matrix is formed mainly by sericite, and fine-grained quartz. Ore minerals (chalcopyrite, pyrite - also var. bravoite, tennantite-(Fe), uranium-bearing leucoxene) form disseminations and veinlets in sandstones. Supergene minerals of Fe, Cu and U (chalcocite, yarrowite, uranophane-α, goethite, malachite, baryte, anglesite and cinnabar) fill microscopic cavities and cracks in the rock. Based on the chemical composition, the studied pyrite can be divided into several groups: a) pyrite with a minimum content of admixtures (composition almost corresponding to the formula FeS2; b) As-bearing pyrite; and c) Ni- and Co-bearing bravoite. Arsenic most likely enters the anionic position of pyrite by the substitution As1-→S1-, and is probably present in solid solution. Zonality of bravoites is caused by ranging in Ni content and the corresponding fluctuations in Fe content (negative correlation), at a relatively constant Co content. Studied bravoites represent a nice example of the preferred concentration of Ni at the edges of the crystals and growth zones. Formation of uranophane-α documents the neutralisation of the environment during weathering of sandstones. Precipitation of baryte and anglesite caused an increase in the pH of the environment (from acid to the slightly basic), which allowed the precipitation of uranophane-α and malachite.
