Sedimentological characterization of part of the continental shelf. Folk classification (7 classes).
Volcanic centres in the Portuguese offshore, located between the Mid-Atlantic Rift zone (Azores archipelago) and the continental margin.
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.
9 chrono-stratigraphic surfaces (tops) obtained from seismic reflection data calibrated by drill-holes and interpreted with geological and other geophysical data produced under the scope of a PhD Thesis.
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.
The onshore wind potential map of mainland Portugal contains the mapping of the main wind parameters at two reference heights, 20m and 80m such as the average wind speed (m/s), Incident Wind Power Flow (W/m2), Weibull parameters: Scale factor A (m/s) and Weibull Form factor k (dimensionless) and the map of the annual number of hours at full capacity (NEPs) of a standard reference turbine. Due to the advancement of wind technology, wind farms are starting to operate with wind turbines with hub heights at least, 100m high. In this sense, the renewable wind mapping (NEPs) at 100m is also available, taking into account the current actual technology.
