Final Report of the Project „Data Acquisition from the Deep Horizons of the Rožná Mine“ presents the results of the study of rock mass properties with respect to the presence of a significant tectonic zone. The study focused on the change of properties in the vicinity of the so-called first zone of the Rožná deposit, but also on the change of these properties with a depth of 12–24. floor of the former mine, 550-1200 m below the surface. Realized works included geological, petrographic, geochemical description of the rock environment, geophysical work (esp. seismics), study of physico-mechanical properties of rocks, transport experiments and deposit revalidation of the Rožná deposit. All work was carried out for the purpose of describing the studied zone and its manifestation with an emphasis on ensuring the safety of the potential location of the deep geological repository.

This report summarizes the work and partial results made under the Public Procurement Obtaining Data from the deep horizons of the Rožná Mine in the first phase of the third and fourth subdivisions from February to November 2018. These are in particular technical works (boreholes, access to corridors),seismic measurements, sampling for laboratory analysis (physical-mechanical properties of rocks, breakage fills, bearing revalidation), structural characterization of the rockanalytical work on all samples taken. Parallel to these works3D models are being prepared, especially data preparation for modeling.
New data on the origin of the Fe-Cu-As skarn deposit at Obří důl, West Sudetes, Bohemian Massif

The Obří důl Fe-Cu-As sulfide deposit is hosted in metamorphosed lenses of marble, calc-silicate rocks and skarns. The deposit is located up to a few hundred meters away from the contact of the large, late-orogenic Variscan Krkonoše-Jizera Plutonic Complex (KJPC). Mineralogical and fluid inclusion studies of the Gustavská ore lens show that the main sulfide stage, dominated by pyrrhotite, chalcopyrite and arsenopyrite, originated from water-rich hydrothermal fluids with salinities up to 8 wt.% NaCl eq. at temperatures ranging from 324 to 358°C.These fluids replaced mainly the carbonate-rich lithologies. The 34S values indicate a magmatic source of sulfur and Re/Os dating of molybdenite are consistent with simultaneous formation of the main sulfide stage ore and the KJPC.
Limnology of the Na Zeleném Brook in the Slavkov Forest
Krám, Pavel ; Senoo, T. ; Beneš, F. ; Čuřík, Jan ; Veselovský, F.
The contribution examined stream hydrochemistry and hydrobiology of the catchment occupied by spruce forest and underlain by amphibolite. The Na Zeleném catchment exhibited favourable hydrochemical conditions and high biodiversity of macroinvertebrates in contrast to another spruce catchments (Lysina and Pluhův Bor) situated nearby but underlain by geochemically different bedrocks (base-cation poor granite and Mg-rich serpentinite).
Fate of smelter dusts in temperate and semi-arid soils
Ettler, V. ; Jarošíková, A. ; Mihaljevič, M. ; Kříbek, B. ; Veselovský, F. ; Penížek, V. ; Vaněk, A. ; Šráček, O. ; Matoušek, Tomáš ; Mapani, B. ; Kamona, F. ; Nyambe, I.
Our results indicate that, compared to semi-arid areas (where inorganic contaminants are rather immobile in soils despite their high concentrations), a higher potential risk exists in smelter-affected humid areas, where metal(loid) contaminants can be easily released by extensive weathering of particulates in the soil systems.
Flux Fluxes in the Amphibolite Basin On the Green at the Marianske Lazne Water Works
Krám, Pavel ; Veselovský, F. ; Čuřík, Jan ; Myška, Oldřich
The paper is about hydrology and hydrochemistry of the Na Zelenem catchment forested by spruce stands which growso n substrate formed by Cambisol on amphibolite. This catchment is characterized by fairly favorable hydrochemical conditions for terrestrial and aquatic biota. The catchment is able to effectivetely neutralize incoming acidic atmopheric deposition mainly due to chemical weathering reactions involving divalent base cations, calcium and magnesium. Mean average precipitation to the Na Zelenem catchment was 790 mm/yr based od 5 year studied period and mean surface runoff was 193 mm/yr in the last two years. Runoff was between 24 and 27% of annual precipitation input to the catchment in the last two years. The catchment accumulated less than 20% of total nitrogen input in bulk precipitation. About 36% of nitrogen left the catchment via surface runoff. About half of the nitrogen output was in the form of nitrate and about half in the form of dissolved organic nitrogen.
Drainage water chemistry in geochemically contrasting catchments
Krám, Pavel ; Myška, Oldřich ; Čuřík, J. ; Veselovský, F. ; Hruška, Jakub
Three small forested catchments, each underlain by geochemically contrasting silicate rock types, were studied in the Slavkov Forest, western Czech Republic. Hydrochemical patterns were ascertained by concurrent stream water and soil water sampling. Th e catchments served as valuable representatives of contrasting terrestrial and aquatic ecosystem resilience to anthropogenic acidifi cation.
