The underground geothermal conditions can be presented, irrespective of the aquifers' position, with the appropriate geothermal maps. This map represents the expected temperatures at a depth of 2000 m and is made with data from 240 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 2000 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 the anomaly is not so much visible 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.

Karte prostorske porazdelitve vrednosti spremenljivk vezanih na temperaturo zraka so narejene na osnovi meritev klimatoloških meteoroloških postaj, ki so v obravnavanem obdobju neprekinjeno delovale vsaj deset let. Za računanje vrednosti spremenljivk vezanih na temperaturo zraka v pravilni mreži z ločljivostjo 100 m x 100 m je bila uporabljena metoda optimalne prostorske interpolacije, ki upošteva povezanost obravnavane spremenljivke z nadmorsko višino in preko izbrane okolice upošteva tudi vpliv mikrolokacije. Zaradi majhne gostote mreže opazovanj, je vpliv mikrolokacije možno upoštevati le v manjši meri.

The underground geothermal conditions can be presented, irrespective of the aquifers' position, with the appropriate geothermal maps. This map represents the expected temperatures at a depth of 1000 m and 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.

The underground geothermal conditions can be presented, irrespective of the aquifers' position, with the appropriate geothermal maps. This map represents the expected temperatures at a depth of 5000 m and is made with data from 192 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, especially in magmatic and metamorphic rocks. 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 5000 m a stronger positive anomaly is in the northeastern part of Slovenia, from the line Maribor-Rogatec to the east. 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, especially in the western mountainous parts they are lower than expected mean values for the continents.

Podzemni geotermični pogoji se ne glede na lego vodonosnikov prikazujejo s primernimi geotermičnimi kartami. Ta karta predstavlja pričakovane globine do izoterme 150 °C in je izdelana s podatki iz 191 vrtin. Na nek način je inverzna tistim navadnim temperaturnim kartam, ki kažejo temperature v določenih globinah. Izdelana je na podlagi izmerjenih temperatur v dostopnih vrtinah po celi državi. Ker pa je temperaturno polje odvisno od geološke sestave v globinah in tektonskih značilnosti, je potek izolinij rezultat številnih vplivov, kot so toplotne prevodnosti kamnin, prepustnost in razpokanost kamnin, ki se vsi odražajo v izmerjenih temperaturah v vrtinah. Seveda pa je prepustnost in razpokanost kamnin vse manjša v večjih globinah, ki so za to karto v zahodni in južni ter delu severne Slovenije že kar velike do te izoterme. Porazdelitev vrtin, ki so bile uporabne za meritve temperature, pa je zelo neenakomerna in po globinah različna. Karta globin do izoterme 150 °C prikazuje pozitivno anomalijo v severovzhodnem delu Slovenije. Kot posledica tanjše Zemljine skorje na tem območju in višjega konduktivnega toplotnega toka iz plašča Zemlje, so tam najvišje temperature, s tem pa so obratno najmanjše globine do izoterme 150 °C.
