Volcanic centres in the Portuguese offshore, located between the Mid-Atlantic Rift zone (Azores archipelago) and the continental margin.
-
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.

QAFI is a database of faults with geological evidence of proven activity during the Quaternary period (the last 2.6 million years according to the limit officially established by the SQS in 2009) of the Iberian Peninsula.

Geology and Geomorphology of the portuguese offshore of the Pre-Quaternary, 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 .

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.

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.

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).

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.
