  • Geological Map of Portugal at scale 1:50 000, consisting of sheets published at this scale in paper and/or digital format. Includes geological maps of the Madeira and Azores Archipelagos.

  • Database that stores and catalogues thin sections and polished surfaces, as well as the corresponding source samples, providing a valuable resource for the scientific community.

  • 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.

  • The Biomethane Atlas serves to support the identification of the most favorable locations for the implementation of biomethane production units, considering proximity to biogas sources (potential producers), potential consumers, and/or the gas network. It is developed using GIS software for mainland Portugal. The analysis is performed to identify clusters of producers/consumers in proximity, considering the division of the country into a 20km² grid (278 grid squares in mainland Portugal). For each of these, the current potential quantity of biomethane production in m³/year was estimated for the following types of potential producers: (1) Waste and Wastewater: municipal waste landfills, industrial waste landfills, and wastewater treatment plants; (2) Agro-industry: Other food products; Milk; Breweries; Slaughterhouses; Tomatoes; Juices/Salads; Rice husks and Dried fruits; (3) Olive mills and wineries: Olive pomace; Olive mills; Wineries and distilleries; (4) Intensive Livestock Farming: Poultry; Ruminants and Pigs; (5) Agricultural Byproducts: Tomatoes; Corn; Rice paddies; Olive grove pruning; Orchard pruning and Vine pruning. The following potential consumers were considered: (1) Refineries and CCGT Combustion Plants; (2) Industry: Glass; Chemical; Cement; Ceramics; Paper/Cardboard; Agri-food and Textile; (3) Vehicle gas refuelling stations; (4) Autonomous Gas Units; and (5) Injection points in the natural gas grid. A dimensionless index was developed that characterizes each grid square according to its suitability and ranges from 0 to 100 (100 is higher/better). The index can be viewed only for producers, for consumers, and for the combination of producers and consumers. A cell with many potential producers of high volumes of biomethane and potential consumers will have a higher value in the index. The location of production projects and areas with limitations for the application of digestates in soils are also shown. The Atlas does not replace case-by-case analysis of project location or licensing. It should be used for informational purposes only. The scale of analysis used is limited by the resolution and accuracy of the underlying information.

  • Location of structures resulting from the submarine fluids emissions, such as: mud volcanoes (methane hydrates); Pockmaks (methane) and hydrothermal vents (fluids enriched in salts and metallic elements), located between the Mid-Atlantic Rift zone (Azores archipelago) and the continental margin.

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

  • 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 .

  • Geological and mining model of the Lousal mine and volcanogenic massive sulfides ore lenses (Iberian Pyrite Belt) under the scope of a PhD Thesis.

  • 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.
