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.
Manuscript of the geological maps published at scale 1:50 000, and of many surveys of dispersed areas that requires validation before publication.
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.
COMET's Database. The dataset for Portugal was updated in the framework of project CSA-GSEU, WP3 Geoenergy, Geological storage thematic working group.

Geological map data of the Algarve Region at scale 1:100 000 modified according to INSPIRE data specifications for the Geology theme. Layers depicting Geologic Units are classified according to ages and lithologies from INSPIRE vocabularies.
The Portuguese Mineral Occurrences and Resources Information System (SIORMINP) provides access to geoscientific, technical and economic information on occurrences, reserves and resources, associated commodities, geology, mines, mining activities, mining wastes and areas with mining potential known in mainland Portugal.
Geological map data of Portugal at scale 1:200 000 modified according to INSPIRE data specifications for the Geology theme. Layers depicting Geologic Units are classified according to ages and lithologies from INSPIRE vocabularies. Sheet 8 has been replaced by the most recent cartography produced within the scope of the Geo_FPI project. Sheet 7 includes the most recent cartography of the Algarve region. It is also intended to prepare the cartography of sheets 3 and 5 as soon as they are published.
