  • Areas that evidence the occurrence of submarine landslides, located between the Middle Atlantic Rift zone (Azores archipelago) and the Continental margin.

  • Geology and Geomorphology of offshore Portugal in the Quaternary period, using as reference the Geological Chart of the Immersed Area, Scale 1: 2 000 000, of the Geological Chart of Portugal, Scale 1: 1 000 000. National Laboratory of Energy and Geology (LNEG) 2010 .

  • QAFI is a database of faults with geological evidence of proven activity during the Quaternary period (the last 2.6 million years according to the limit officially established by the SQS in 2009) of the Iberian Peninsula.

  • Volcanic centres in the Portuguese offshore, located between the Mid-Atlantic Rift zone (Azores archipelago) and the continental margin.

  • Sedimentological characterization of part of the continental shelf. Folk classification (7 classes).

  • The Geothermal Atlas of Mainland Portugal is a mission-driven project of fundamental importance for the geothermal knowledge of the country, systematically carried out at the National Laboratory of Energy and Geology (LNEG) for over 30 years. It was created following other mapping projects, incorporating diverse information from various data sources obtained for different purposes, from different institutions, and harmonized and processed in a way that allows it to be applied to information, dissemination, training, promotion, and research on geoenergy in mainland Portugal, thus serving as a lever for the sector's development. It constitutes a dynamic and constantly updated research effort, integrating various parameters from diverse origins applicable to geoenergy studies. Its integrated and homogenized processing allows for a visualization of the country's geothermal characteristics on a national scale and can be used to determine geothermal potential at various scales. As sources of information for the production of geothermal mapping of mainland Portugal, processed and directed towards the various types of geothermal energy and geothermal exploitation, the first works began more than 40 years ago, forming the basis of Portuguese contributions to successive European Atlases of Geothermal Resources, the last of which was published in paper in 2002 with updates published in 2025 in the European Geological Data Infrastructure. This information is constantly complemented by additional geothermal information, whose original acquisition was made for geothermal purposes, and also by information acquired for other geoscientific objectives. The incorporation of information is done according to established criteria.

  • Database that stores and catalogues thin sections and polished surfaces, as well as the corresponding source samples, providing a valuable resource for the scientific community.

  • COMET's Database. The dataset for Portugal was updated in the framework of project CSA-GSEU, WP3 Geoenergy, Geological storage thematic working group.

  • The 3D geological model was created, in the framework of ProMine project, to integrate the geological knowledge of an extensive geophysical and geological research conducted in the Portuguese part of the Iberian Pyrite Belt. It was applied to the 100 x 25 km large Neves Corvo project area. The main purpose of the model was to foresee the existence of other massive sulfide deposits as to the well-known Neves Corvo orebodies. Stratigraphic and structural model based on geological, geophysical and drill hole data produced in the framework of the ProMine project.
