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

  • 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.

  • 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.

  • Manuscript of the geological maps published at scale 1:50 000, and of many surveys of dispersed areas that requires validation before publication.

  • This map was developed to integrate the 2nd version of the PNS - Portuguese Natural Stones - Portal. It contains points, which correspond to the geographic coordinates (central) of the quarrying site(s) where the natural stones included in PNS Portal are quarried. Selecting each point on the map allows access to a table, which includes: - stone code on the PNS Portal; - main commercial names; - stone type; - petrological family; - geographic coordinates (EPSG 4326); - link to the stone’s Technical Sheet, on the PNS Portal.

  • The national radiometric map began to be drawn up in the 1950s for uranium prospecting and represents the natural radioactivity measurements based in old and new surveys and calibration and harmonization of these data. The mapping of the country's natural radiation allows supporting exploration for mineral and geothermal resources, geological mapping and hazard studies.

  • Geological map data of Portugal at scale 1:1 000 000 modified according to INSPIRE data specifications for the Geology theme. Layers depicting Geologic Units are classified according to ages and lithologies from INSPIRE vocabularies, faults and geomorphologic features are also available. This dataset was formerly prepared in the framework of the OneGeology-Europe project. The faults are harmonized based on the work done within the scope of the HIKE project.
