Basic geological map of Yugoslavia presents lithological and stratigraphic characteristics of rocks, their relationships, age and other. It is a key to the understanding of the geology of Slovenia. It consists of 23 sheets, scale 1: 100.000.
Mineral deposits and resources
Data of Geological map were reclassified into classes of IAH classification on the base of hydrogeological characteristics. IAH classification is based on description of the hydrogeological units. Firstly, based on extensiveness and productivity and secondly on type of porosity. The purpose is to provide assistance to the strategy of groundwater exploitation as to protection and water resources management.
Layer Boreholes shows the localities where structural boreholes were drilled.
Geological Units are polygons, defined by equal composition (lithology) and age.
Layer Geomorphologic Features shows the location of various types of geomorphological phenomena. Only point data are included.
Layer shows discontinuities in the geological structure, and characterizes them according to their type and observation method.
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.
