Abstract

A new geological map of the Badajoz province (SW Spain) at a 1:100.000 scale is presented including substantial changes with respect to previously published cartographic compilations. The main modifications are related to the reference stratigraphic sequences and their chronology. The new stratigraphic and paleonthological data gathered reveal that large areas of the Ossa-Morena Zone (ZOM) previously attributed to either Precambrian, Ordovician or even Devonian are in fact of Cambrian age. This allows for a new stratigraphic column and a drastic simplification of the cartography by eliminating many of the 'Units' and 'Domains' that appeared in previous maps. In the areas of the La Codosera and Sierra de la Lapa (Central-lberian Zone), formations previously assigned to the Ordovician and Silurian have been found to be Upper Devonian to Carboniferous in age. Finally; the existence of a Devonian to Carboniferous continuous basin extending over the northern ZOM and southern ZCI is postulated. The changes introduced in the new geological map should have important implications in palinspastic models of the Hercynian paleogeography.
