Geological Map of Spain and Portugal at scale 1:1.000.000

The Geological Map of Spain and Portugal at a scale of 1:1 000 000 was compiled from various sources. The continental part of the map was compiled from previous 1:400,000 scale syntheses prepared for each of the major geological units in Spain, namely the Variscan Massif, the Pyrenees, the Betic Cordillera, the Cantabrian and Iberian Cordillera and the basins of the Duero, Tagus and Ebro rivers, and the 1:200,000 scale geological cartography carried out in Portugal. A group of experts simplified this initial information and compiled it according to the common legend defined for the map. The mapping of the Spanish islands was elaborated from the original information of the IGME cartographic series at various scales and the geological mapping at scales 1:25 000 and 1:50 000 for the Portuguese Atlantic islands. The geological mapping of the continental margin was elaborated from several cartographic sources at different scales: Geological Maps of the Spanish Continental Shelf at scale 1:200 000 and the Geological Map of the Quaternary at scale 1:1 000 000 published by the IGME, the Geological Map of Portugal at scale 1:1 000 000 000 (LNEG-LGM) including the new version of the Geological Map of the Portuguese Continental Shelf at scale 1:2 000 000 000 and the Geological Map of the Bay of Biscay (BRGM). This cartography was complemented with geological data acquired in oceanographic campaigns carried out in the framework of different research projects with the participation of the IGME and the LNEG, as well as the Spanish Continental Shelf Expansion Project, in accordance with the United Nations Convention on the Law of the Sea.
