  • The Geological Map of Portugal at a scale of 1:1 000 000, published by LNEG in 2010, constitutes the synthesis document of the current knowledge about the geology of mainland Portugal and all insular territory: the Azores and Madeira Archipelagos. This map includes for the first time the geology of the continental shelf around mainland Portugal, drawing on over 30 years of marine geological research. The map comprises: a Geological Map of Mainland Portugal, a Geological Map of the Continental Shelf, and separate geological maps for the Azores and Madeira archipelagos (all at a scale of 1:1 000 000). Additionally, it includes a Neotectonic Scheme of Mainland Portugal with Hypsometry at a scale of 1:4 000 000, a Tectono-Stratigraphic Scheme at 1:5 000 000, and a Location Map at 1:20 000 000.

  • Volcanic centres in the Portuguese offshore, located between the Mid-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 .

  • Geological Map of the Algarve Region, scale 1:100 000, produced by the Geological Survey of Portugal in 1992, as part of systematic geological surveys of the Meso-Cenozoic coast of the Algarve.

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

  • This product was developed by LNEG with a view to the future identification of “Renewable Acceleration Areas” for the deployment of renewable electricity production plants in Mainland Portugal. The work took place within the scope of an informal Working Group, coordinated by LNEG and involving: the Portuguese Environment Agency (APA), the General Directorate of Energy and Geology (DGEG), the General Directorate of Territory (DGT), the Institute of Conservation of Nature and Forests (ICNF) and the General Directorate of Cultural Heritage (DGPC). The map identifies the areas in m2 of mainland Portugal with the least sensitivity (environmental, cultural heritage and other) which as such may be considered in the definition of future renewable "Acceleration Areas" within the framework of the revised RED Directive (Renewable Energy Directive. As these areas are not covered by exclusion conditions regarding the preservation of environmental and heritage values (among other), a simplified permitting process for renewable power production plants (solar photovoltaic and wind) could be established, thus allowing to accelerate its implementation without compromising other environmental and territorial values. The mapped areas are preferred areas from the point of view of simplifying the permitting process, but they are not exclusive. In other words, renewable power plants can be implemented in other locations following the normal permitting process. It should be noted that the presented results reflect the situation as of June 2023, and much of the information used is dynamic in nature, meaning this product must be periodically updated. This document is complemented with several electronic Geographic Information System (GIS) files containing the supporting data produced/compiled and collected. Last but not least, this first mapping focuses exclusively on non-artificialized areas. Although the implementation of renewables in a distributed manner in a built/artificialized environment is essential for the country, the analysis of this scope is carried out in another work.

  • 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.

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

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