The following exogenous geological processes and phenomena are widespread in the territory of Lithuania: sea abrasion and reshaping of lakes and water reservoirs, erosion of rivers and ditches, planar erosion; suffusion; karst, swamping; landslides; relief reshaping, etc. Endogenous processes – earthquakes and current tectonic movements - are also recorded in Lithuania. The emergence and development of these processes affect the ecogeological conditions of the territories, endanger the stability of the territories and the structures in them, human economic activity and safety.

The catalogue of geological survey reports consists of the results (reports) of geological mapping, in-depth surveys, seismological monitoring, ecogeological surveys, hydrogeological surveys, underground hydrosphere monitoring and other geological surveys. Geological surveys include drilling of wells, geophysical or engineering geological (geotechnical) surveys, rock, water and other samples that reveal factual data on subsoil layers and their properties, extent of surface pollution, groundwater quality and soil suitability (e.g. , for foundations of multi - purpose buildings).

Permits are issued to natural and legal persons or groups of such persons operating under joint activity agreements. According to the Underground Law of the Republic of Lithuania, only resources that have been explored in detail and approved in accordance with the procedure established by the Lithuanian Geological Survey may be used. The data consists of the name of the subsoil stock or part thereof, the name of the wellfield and the code in the Subsoil Register; information on approved minerals (other than hydrocarbons), groundwater resources and subsoil cavities.

Permits shall be issued to natural and legal persons or a group of such persons specifying the types of research to be carried out. Authorization may be granted for one or more types of research. Permits are issued for direct and remote (except hydrocarbon) geological exploration of the underground depths, which are divided into the following types according to the object, research methods and purpose of the underground exploration: mining and exploration (of which: hydrocarbons; ores); groundwater exploration and exploration of all types (including thermal energy of the subsoil); search and exploration of subsoil cavities; subsoil mapping (geological; hydrogeological; geochemical; aerophotogeological; ecogeological; engineering geological; mineral resources; geophysical); engineering geological (geotechnical) research; ecogeological research; geophysical survey; other uses.

Groundwater level is measured daily in 74 wells with electronic sensors, 20 wells are equipped with telemetric level data transmission systems. Groundwater levels in a given area depend on meteorological and geological conditions. Shallow (up to 5 m) groundwater accumulating in clayey sediments, the level of which rises and falls by several meters during the year, is most likely to react to changes in meteorological conditions. In deeper water, the change in level is only a few centimeters.

Groundwater levels are measured daily in boreholes with electronic sensors. Cclimate change impact on groundwater level regime and groundwater resources could be addressed by analyzing continuous and long-term groundwater level measurements data in generalised format. Therefore, the calculated average monthly groundwater levels data are presented.

The geomorphological map of Lithuania is a graphical representation of the age and origin of Lithuanian relief and the morphometry of surface forms. The colors on the map show the origin of the relief: brown - the surface created by the glacier, green - the relief formed by glacial melting rivers, and blue - the relief formed by glacial lagoons, the relief formed by light rivers and lakes in light green and blue, yellow - wind-blown relief - relief due to swamping, etc. Specific relief forms (drumlins, platelets, rhinos, clones, etc.) are shown by colored lines corresponding to the genetic color. The morphometry of the relief is shown by special signs: the hillyness is shown by a grid of brown lines, and the undulating and concave surface of the surface is marked by black symbols. Red bright lines show the limit of the maximum spread of the last - Nemunas - glacier and the limits of the Baltic stage of this glacier and the phases of Southern, Central and Northern Lithuania. The age of the relief is indicated by a darker shade of color indicating the genesis. The map has been supplemented with information on the geomorphological zoning of Lithuania: the descriptive data show: the names of geomorphological areas, districts, sub-districts and micro-districts. Lithuanian geomorphological map M1: 200,000 covers the entire territory of Lithuania.

The map of the boundaries of Lithuanian karst regions M 1:50 000 shows the boundaries of the spread of karst and karst suffusion process in the territory of Lithuania. The karst process in Lithuania is related to the dissolution and removal of gypsum. During this process, voids are formed in the depths of the earth, and superficial karstic forms can be formed on the surface - sinkholes, bends, collapses, etc. The map was created by analyzing and determining the prevalence of karstic relief forms and taking into account the available geological information (presence of karstic rocks, gypsum thicknesses, gypsum-covering rock thicknesses, etc.).

The geological map of the Quaternary shows the lithological (material) composition, genesis (origin) and age of the sediments forming the surface of the territory. The color on the map indicates the origin of the deposits, and the darkness of the color reflects the age of the deposits (the darker the color, the older the deposits). The age is additionally indicated by bright red lines marking: the maximum spread of the last - Nemunas - glacier, the edge of the Baltic stage of this glacier and the boundaries of the southern, central and northern phases of the Baltic stage glacier. The lithological composition of the sediments is marked with dotted and dashed or other symbols. The geological map of the Lithuanian Quaternary covers the entire territory of Lithuania.
