Currently, there are over 200 officially registered sulfur springs in Slovakia, most of which cold hydrogen sulfide with a characteristic strong odor rotten eggs. Their typical inhabitants filamentous sulfur-oxidizing bacteria. The aim this study was to identify the major bacterial populations inhabiting Slovakia using combination non-cultivation and cultivation approaches. Non-cultivation analyses revealed high variability bacteria Slovak springs. Sulfur mats were usually dominated by...

The sulfur cycle participates significantly in life evolution. Some facultatively autotrophic microorganisms are able to thrive extreme environments with limited nutrient availability where they specialize obtaining energy by oxidation of reduced compounds. In our experiments focused on the characterization halophilic bacteria from a former salt mine Solivar (Presov, Slovakia), high diversity cultivable was observed. Based ARDRA (Amplified Ribosomal DNA Restriction Analysis), at least six...

The study aims to reconstruct the crystalline parent rock assemblages of Eocene Strihovce Formation (Krynica Unit) and Mrazovce Member (Raca deposits, based on heavy mineral suites, their corrosive features, geochemistry garnet tourmaline, zircon cathodoluminescence (CL) images, exotic pebble composition. Both units are an integral part Magura Nappe belonging Flysch Belt (Outer Western Carpathians). Corrosion signs observable minerals point different burial conditions and/or diverse sources....

The provenance of the Proč and Strihovce sandstones is crucial for understanding relationship between Pieniny Klippen (PKB) Flysch (FB) belts in easternmost part Western Carpathian realm. Detrital Cr-spinels these tectonic units were assertively interpreted as sourced from southern sources representing Meliata mélange. In this study, we use geochemistry detrital chromian spinels to identify mafic ultramafic source sediments compare them each other. Simultaneously, their chemical compositions...

Biotite from Čierna hora Mountains granitoids (Western Carpathians, Slovakia) and estimation of water contents in granitoid melts is the dominant ferromagnesian mineral different granites Mountains, Western Carpathians (Slovakia). A higher content Fe 3+ (up to 20 %) characteristic for biotites I-type Sokoľ Sopotnica bodies contrast S-type Ťahanovce showing decreased amount (around 5 %). The Fe/(Fe + Mg) ratio massifs between 0.47 0.54 rather low with respect that biotite [Fe/(Fe = 0.55-0.63]...

Detrital chromian spinels in sedimentary rocks provide much information concerning the tectonics of their parental ultrabasic rocks. Chromian occurring Eocene to Oligocene deposits from Magura Nappe were examined some constraints on history Basin. The is a part Flysch Belt belonging External Western Carpathians. separated by narrow zone associated with Pieniny Klippen and divided into three principal tectono-lithofacies units (from S N): Krynica, Bystrica Rača units. Cr-spinel common...

Abstract Caves are unique sedimentary archives that may record the evolution of surrounding landscape. In this study, we applied combination mineralogical data on allochthonous sediments with digital modelling isobase surfaces to reconstruct multi‐phased geomorphological development karst Harmanecká dolina Valley. The cave contain quartz and translucent heavy minerals (HMs) such as tourmaline, garnet, rutile, apatite, zircon, pyroxene, amphibole, staurolite, spinel, monazite, corundum,...

Detrital heavy minerals separated from the Malcov Fm. deposits (Magura Nappe) indicate their source rocks and areas. The mineral assemblages predominantly consist of garnet, zircon, tourmaline, rutile Cr-spinel. EPMA analyses reveal a few groups garnets: zoned unzoned Grs almandines, Prp-Sps Prp Sps almandines rare spessartine grains (~85 mol% Sps). garnet composition indicates that gneisses, mica schists, amphibolites granites were main rocks, but low-grade metapelites with Mn...

Abstract Strong tectonic remobilisation and shear zone development are typical features of the easternmost part Veporicum unit in Western Carpathians. The granodiorite mylonites area Rolovská (Čierna hora Mts) underwent a complex polystage evolution during Hercynian Alpine orogenies. Deformation latter reached greenschist facies under metamorphic conditions. Mylonites macroscopically foliated rocks with stretching lineation bands. Structurally different mylonite types, ranging from...

The cave deposits from the Mošnica Cave located on northern slope of Nízke Tatry Mts. were analysed by sedimentological, petrographical and mineralogical methods. Based study sediments are composed dolomite, quartz, muscovite, amphibole, chlorite, calcite, Kfeldspar plagioclase. Heavy mineral assemblage is formed garnet, zircon, apatite, monazite, tourmaline, staurolite, rutile, titanite, epidote, sillimanite, allanite, andalusite barite. Opaque minerals represented ilmenite, pyrite,...

The provenance of Devonian sandstones the Padeha Formation (Fm.), Eastern Alborz in Iran, has been investigated by standard heavy‐mineral analysis and tourmaline rutile geochemistry. Heavy‐mineral assemblage is dominated ultra‐stable tourmaline, zircon, rutile, while unstable species are completely absent. Fm. show a very high value zircon‐tourmaline‐rutile index signalizing either strong weathering source area(s) or their recycled origin older Early Palaeozoic formations. Detrital shows...
