  • 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 .

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

  • Stratigraphic and structural model of the Neves-Corvo Region produced in the framework of the SMART EXPLORATION Project, based on geological, geophysical and drill hole data. It has three stratigraphic surfaces: Base of Mértola Formation, Top of Phylite Quartzite Formation, and in the Neves-Corvo mine region, the contact between the upper and lower Volcanic Sedimentary Complex is available.

  • 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.

  • The marine energy potential maps for mainland Portugal consists of the mapping the main wind and wave parameters for the offshore environment at the height of 100m (offshore wind resource) and at surface (wave energy resource). The offshore wind resource is performed with a sophisticated mesoscale atmospheric model, capable of describing the main wind phenomenology near the Portuguese coast, and contains the mapping of the average wind speed [m/s], Wind Power Flux [W/m2] and the map of the annual number of hours at full capacity NEPS of a standard reference turbine as well as the NEPS maps [h/year] for specific type of bottom-fixed wind turbine systems - "Jacket" and "Monopile" or Floating – WindFloat. The offshore wind resource maps represent the climatology of the wind resource as well as characteristics of the wind phenomenology associated to the land-sea interaction along the Portuguese coast. Regarding the wave energy maps, the estimation of the wave energy resource is based in estimating the main sea-wave characteristics and the wave energy production for standard different wave system types – oscillation water column converter; floating two-body heaving converter bottom-fixed oscillating flap converter. The maps of the wave energy resource are a merging of observational data (boys) and information from the ONDATLAS database as well as data from numerical modeling with the MAR3G model all with 10 years of data . This way the wave energy resource maps describe the main characteristics of the average wave resource for a period of 10 years, which is representative of the sea state climatology of Portugal. All wave energy maps are expressed in [kW/m]. Also, all wind and wave energy resource maps are processed with a high spatial resolution of 1km x 1km from the coast up to the bathymetric of 300m. Some wind and wave energy maps are freely available to download in a course but larger grid area (5Km x 5Km). In time, the offshore wind maps will include higher heights.

  • 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).

  • Geological model of the volcanogenic massive sulfides deposit of Lagoa Salgada (Iberian Pyrite Belt) under the scope of a PhD Thesis.

  • Geological and mining model of the Lousal mine and volcanogenic massive sulfides ore lenses (Iberian Pyrite Belt) under the scope of a PhD Thesis.
