Geology at a glance and a map of the zone

What lies beneath the water and around it? An overview in tiles, a map of mine workings, deposits, environmental burdens, boreholes and gold finds, and how to read the data

The overview is based on public registers and atlases of the State Geological Institute of Dionýz Štúr. The search covers a zone around the water of all fishing districts of the stream (6 km of line in total): stream samples within 1 km, boreholes, mine workings and burdens within 3 km, ore occurrences within 5 km, geothermal sources within 10 km.

The line is the water of the fishing district, the light band is the 3 km zone in which boreholes, mine workings and burdens were searched for. The map shows the nearest objects (at most a few dozen from each register), not all of them. The points correspond to the position in the register; area objects are marked by their center.

How to read these data

Zone and distance. The distance is measured from the line of the water to the point in the register (to the center for areas), with an accuracy of tens of meters. Counts apply only to the zone, not to the whole catchment.
Percentile. For chemistry, the highest value is compared with all atlas samples in Slovakia. It is not a legal limit or a health risk assessment; the atlases are historical (published: surface waters 2015, groundwater 1996, river sediments 1999).
Limit of quantification. Many samples have a value at the lowest level the laboratory can determine; such results mean "below the limit". For these, the position in the distribution is an estimate.
Panning concentrates. Only samples with a find are recorded. The number of grains in a concentrate is not the gold content in grams per tonne.
Relation to water. A mine working, landfill or burden nearby proves nothing about the quality of the water in the stream. It serves as a prompt for attention and a starting point for further investigation.
Sample points. The area and raster maps of ŠGÚDŠ cannot be downloaded as points, so along the line of each fishing district the value is looked up at points roughly every 3 km. It is a sample of the line, not a continuous record; a very short section may have a single point.
Atlas rasters. The chemistry of water and sediments is an interpolation of measurements in a sampling network (Geochemical Atlas of Slovakia). The value at a point is a modeled estimate for the surroundings, not a measurement in the water. The percentile compares the average of this stream with all sample points on streams in Slovakia.
Positions and scales. The maps have different scales (1:50,000 to 1:1,000,000), so the level of detail differs between sections. A map outside its coverage means there is no area at that point, not that there is nothing there.

Rocks, groundwater and landscape

What does the water flow over? Geological structure and age of the rocks, groundwater aquifers, relief, climate, soils and geophysical fields

Geological structure beneath the water

Which rock lies beneath the water line (Geological Map of Slovakia 1:50,000), how old it is, how thick the Quaternary cover is and in which tectonic unit the water flows. The bedrock decides the hardness of the water, the bottom, the turbidity after rain and the abundance of springs.

The points follow the water line (for a stream and a basin, fishing district after fishing district). The strip is a cross-section by distance, not a map; the width of a section corresponds to the number of points.

Hydrogeology: aquifers and groundwater

Streams and rivers are fed by groundwater. Hydrogeological maps show in which rocks the water is stored, how permeable they are and what the water in them is like. The data come from ŠGÚDŠ maps, not from measurements at a particular water.

Geophysical fields: magnetics and gravity

Maps of the magnetic field and gravity (ŠGÚDŠ) reveal what lies beneath the sediments and the surface: volcanic bodies, faults and crustal thickness. For an angler they are interesting indirectly: they show where the bedrock changes, and with it the water.

Magnetic anomaly

-52nT

range -56 to -48 nT

Deviation of the Earth's magnetic field from its surroundings. Positive and negative anomalies reveal rocks with magnetite (basalts, basic volcanic rocks) and boundaries in the bedrock.

Bouguer gravity anomaly

-35mGal

residual −1.8 mGal

Negative values lie over thick sediments and under mountains (light crust), positive over dense rocks and thinner crust. It shows the structure of the Earth's crust, not the water.

Chemistry of water and river sediments

What is in the water and on the bed? Trace elements and metals, nutrients, major ions, elements in sediments and groundwater

Surface water chemistry according to the atlas

Modeled composition of the water in the area the fishing district line runs through. The rasters of the Geochemical Atlas of Slovakia (surface waters) are an interpolation of measurements in sampled streams, so they show the typical background of the area, not a measurement in a particular stream.

Water acidity

pH 8.34typical range

Most rivers and streams in Slovakia have a pH of 6.5 to 8.5. More acidic water is found in streams on acidic rocks (granites, quartzites), more alkaline water near limestones.

Water hardness

14.2°dH, hard

Sum of calcium and magnesium (2.54 mmol/l). Hard water is buffered and its pH changes more slowly; soft water is more sensitive to acid rain.

Dissolved substances

401mg/l mineralization

Total amount of dissolved minerals. Clean mountain water has tens of mg/l, lowland and limestone waters hundreds.

Ionic composition of the water

Cations (positive ions)

Elements in river sediments

The Geochemical Atlas of Slovakia (river sediments) describes what the river carries in the fine material on its bed. Sediment collects metals from rocks, ore occurrences and past mining and industry. It is not a legal limit or a health risk assessment: it shows how an element on this stream ranks among streams in Slovakia.

Gold and ore minerals in river sediments

Regional panning prospecting: the heavy fraction was washed out of river gravel and the mineral grains in it were counted. The map of finds is positive: a sample without gold is not listed in the atlas, so the absence of a find is not proof that there is no gold.

Geothermal potential

The Atlas of Geothermal Energy of Slovakia records rock temperature and heat flow from the Earth's interior. It is the potential of the area, not the actual warmth of the water in the stream. Specific geothermal boreholes and springs near this water are in the geothermal energy section below.

Rock temperature with depth

28 / 45 °Cat depths of 1,000 and 2,000 m

increase of 17 °C per km

The line shows the rock temperature; the dotted part is only an extension to the surface. Heat flow 58 mW/m².

Geothermal energy and mineral waters

Geothermal boreholes (wellhead water temperature, yield, chemical type) and sources of geothermal and mineral waters within 10 km. Data on the use and existence of a borehole come from the Geofond register.

Natural radioactivity and radon

How much does the ground radiate here? Gamma radiation of rocks, radon in soil and radon in waters

Natural radioactivity and radon

Airborne gamma-ray spectrometry by ŠGÚDŠ measures radiation from potassium, uranium and thorium in rocks and soil. Granites and some acidic volcanic rocks have the highest values, limestones and floodplains the lowest. Caesium-137 is a remnant of fallout from the Chernobyl accident and nuclear weapons tests.

Gamma radiation dose rate

42nGy/h in air

range 23 to 76 nGy/h

Natural background from rocks and soil; higher over granites and some acidic volcanic rocks, lower over limestones and floodplains.

Radon risk of the bedrock

low

Radon is a natural gas from rocks. The risk concerns buildings and cellars, not the water in the stream; it shows what the bedrock is like.
