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.

Geological map data of Spain and Portugal at 1:1 000 000 scale modified according to INSPIRE data specifications for the Geology theme. Layers depicting Geologic Units are classified according to ages and lithologies from INSPIRE vocabularies.
