Hydrogeological map of Slovenia 1:250.000 represent hydrogeological characteristics of overlaying strata. The identification and classification of strata is based on LAWA classification. Hydrogeological units of LAWA classification are defined on type of porosity and basic petrographical composition. Geological strata with kartic porosity were additionaly classified after karstification stage.

The underground geothermal conditions can be presented, irrespective of the aquifers' position, with the appropriate geothermal maps. This map represents the expected temperature lines at a depth of 3000 m and is derived from Geothermal map - Expected temperatures at a depth of 3000 m, which is made with data from 214 boreholes. It is made on the basis of measured temperatures in accessible boreholes throughout the country. However, since the temperature field depends on the geological structure in the depths and tectonic characteristics, the course of the isotherms is a result of many influences, such as thermal conductivity of rocks, permeability and fracturing of rocks, all of which are reflected in the measured temperatures in boreholes. In this depth also a radiogenic heat production in the rocks has smaller influence. The distribution of boreholes, which were useful for the measurement of temperature, is very uneven and different as regard the depths. Following the expected temperatures at a depth of 3000 m a stronger positive anomaly is in the northeastern part of Slovenia, from the line Maribor-Rogatec to the east, while in the eastern part of the Krka basin there is no anomaly any more. In the northeastern part of the country the anomaly is the result of the thinning of the Earth's crust and greater conductive heat flow from the Earth's mantle. Elsewhere temperatures are much lower.

The harmonized geological map of Slovenia is a simplified version of the 1:250 000 scale Geological Map of Slovenia (Buser, 2009), which was compiled using the Basic Geological Map of Slovenia at a scale of 1: 100.000 (compiled by various authors during the 1960's to 1980's) with the addition of new information by Buser. It is primarily a lithostratigraphic map.The faults were selected for portrayal using two criteria; regional extent and tectonic importance. The map presented here was edited specifically for the purpose of the OneGeology-Europe project by M. Bavec, M. Novak, M. Poljak, M. Trajanova and D. Skaberne.

Map represents the calculated (surface) heat-flow density (HFD) in mW/m2 with topographic correction. It is made with data from 119 boreholes from the measured temperatures in the available boreholes and measured thermal conductivity on cored rock samples from the same boreholes. The pattern of the HFD isolines is affected by numerous parameters, particularly the thermal conductivity of rocks, rock permeability and fracturing, fluid content of the rocks, and all are reflected in the measured temperature gradient in the boreholes.

The underground geothermal conditions can be presented, irrespective of the aquifers' position, with the appropriate geothermal maps. This map represents the expected isoterms at a depth of 1000 m and is derived from Geothermal map - Expected temperatures at a depth of 1000 m, which is made with data from 302 boreholes. It is made on the basis of measured temperatures in accessible boreholes throughout the country. However, since the temperature field depends on the geological structure in the depths and tectonic characteristics, the course of the isotherms is a result of many influences, such as thermal conductivity of rocks, permeability and fracturing of rocks, all of which are reflected in the measured temperatures in boreholes. The distribution of boreholes, which were useful for the measurement of temperature, is very uneven and different as regard the depths. Following the expected temperatures at a depth of 1000 m a stronger positive anomaly is in the northeastern part of Slovenia, especially between Maribor and Murska Sobota and further to the Hungarian border and at Lendava, as well as in a smaller eastern part of the Krka basin. In the northeastern part of the country the anomaly is the result of the thinning of the Earth's crust and greater conductive heat flow from the Earth's mantle.

This map represents the expected isotherms at a depth of 2000 m and is derived from Geothermal map - Expected temperatures at a depth of 2000 m, which is made with data from 240 boreholes. It is made on the basis of measured temperatures in accessible boreholes throughout the country.
