The Geological Survey of Slovenia (Geološki zavod Slovenije - GeoZS) is a multidisciplinary public research institute that operates in various fields of geoscience and conducts basic research and applied activities in Slovenia and abroad, as well as public services in support of the operation of the Republic of Slovenia and the European Union. The GeoZS acquires, stores, interprets and makes available geological data required by the state and society. We are engaged in research on both national and international levels and cooperate with similar organisations in Slovenia and abroad. The GeoZS takes an active part in various EU programmes focused on sustainable living, climate action, as well as efficient and sustainable use of resources and raw materials. We work hard to provide universal accessibility and application of expert knowledge in the society and the economy, transfer research results into practical application, popularise science, spread scientific culture, and raise public awareness. The GeoZS aims for its name to become synonymous with the knowledge of everything that can be found beneath the Earth’s surface. While our top priority is research, we are also creating an environment that will allow efficient transfer of theoretical knowledge into practice, both in Slovenia and abroad. In the long run, three research programmes will continue to form the core of our research: Regional Geology, Groundwater & Geochemistry, and Mineral Resources.
