Mineralogy and genetic aspects of the metamorphosed manganese mineralization at the Július ore occurrence near Betliar (Gemeric Unit, Western Carpathians, Slovakia)

Popis výsledku v původním jazyce

The Julius metamorphosed manganese occurrence is situated near the Betliar village in the Spissko-gemerske rudohorie Mts. (Western Carpathians). Mineralization occurs in the form of manganese carbonate -silicate lenticular body hosted in Lower Paleozoic metasedimentary and metavolcanoclastic rocks of the BystrATIN SMALL LETTER Y WITH ACUTE potok Formation, Gelnica Group, Gemeric Unit. The Mn mineralization dominantly consists of rhodochrosite, pyroxmangite, spessartine, magnetite, clino-suenoite, clino-ferro-suenoite, tephroite, pyrophanite and pyrosmalite-(Mn) alongside with pyrite, pyrrhotite, galena, sphalerite, cobaltite, gersdorffite, siegenite, violarite and minor pentlandite and millerite. Very rare minerals, such as hejtmanite, bafertisite as well as a two recently approved members of the epidote supergroup [ferriandrosite-(Ce) and vielleaureite-(Ce)] were also identified. Significant feature of studied mineralization in comparison with the other occurrences of metamorphosed manganese mineralization in the Spissko-gemerske rudohorie Mts. is the absence of rhodonite. Mineralization at the Julius occurrence originates from heterogenous sediment with occurrence of manganiferous, calcareous, argillaceous and terrigenous material with quartz and Ba-rich minerals locally incorporated by material from a volcanic source. Based on mineralogy and ore textures, two metamorphic stages affecting the final mineral composition of Mn mineralization can be distinguished. Generally, the mineral assemblage was likely formed during the Variscan metamorphic stage in the p-T conditions approximately 420-450 degrees C and pressure 2-4 kbar, as a peak of a metamorphism can be considered the high-grade greenschist facies conditions. Alpine metamorphic phase determined the appearance of veins and veinlets composed of rhodochrosite-chamosite-quartz, pyroxmangite and spessartine.
