[Description of methods used for collection/generation of data] This map has been elaborated based on a compilation of different tectonic features described by other authors in scientific publications, books and PhD theses developed in different sectors of the continental margins of Iberia. The tectonic feature mapping derived from this compilation has been implemented in a Geographic Information System (GIS). In some cases, the structures shown have been redrawn or directly interpreted from the available geophysical information (bathymetry, seismic profiles, and potential fields). The tectonic features included in this dataset were compiled for a tectonic map at scale 1:1,750,000. This work shows an update of the existing knowledge of the main tectonic and volcanic structures along the Iberian continental margins and abyssal plains. The morphotectonic trends around Iberia recorded superposed geodynamic processes linked to the opening of the North Atlantic Ocean since the Mesozoic and the evolution of the Mediterranean Sea during the Cenozoic, as well as the reactivation of Hercynian faults and the formation of new tectonic structures during the Alpine orogeny. The delineation of the different tectonic features included in the dataset is based on the interpretation of the digital bathymetric model and other geophysical data from our own studies, and those from other authors. Accompanying the dataset, a PDF document with the bibliographical references used is also included. This work was supported by the C.N.
