Geological Map of Portugal at scale 1:50 000, consisting of sheets published at this scale in paper and/or digital format. Includes geological maps of the Madeira and Azores Archipelagos.
Delimitation of areas and identification of geological formations with potential for CO2 storage in mainland Portugal and its respective Exclusive Economic Zone (EEZ). The areas were obtained from a combination of historical data (mechanical oil exploration surveys and their geophysical logs and geophysical prospecting using the seismic reflection method), lithostratigraphic interpretation, requirements for storage in saline aquifers, as well as an update of the results of the COMET, CO2STOP and HYSTORIES projects, carried out in the framework of the CSA-GSEU project (WP3 Geoenergy, thematic subgroup CO2 and Hydrogen Storage).
Location of structures resulting from the submarine fluids emissions, such as: mud volcanoes (methane hydrates); Pockmaks (methane) and hydrothermal vents (fluids enriched in salts and metallic elements), 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 Critical Raw Materials Deposits Map in Mainland Portugal is a compilation of the known mineral occurrences and deposits of the most critical raw materials according to the latest list published by the European Commission in 2023.
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.
Prototype of a seamless data model of the Digital Geological Map of Portugal, at scale 1:200 000, in which the mapped units of mainland Portugal were inventoried and organized according to a unified legend (LU). Standardization and harmonization work was carried out between contiguous maps, as well as updating the units through extensive bibliographic research and, above all, leveraging on the experience and knowledge existing at LNEG. The following elements are available: LU code, unit code, unit name, and associated lithological description. This work is under development and reflects the situation as of September 2025.
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.
