Geological map of the Iberian Peninsula. The core of the Iberian Peninsula consists of a Hercynian cratonic block known as the Iberian Massif. On the northeast, this is bounded by the Pyrenean fold belt, and on the southeast, it is bounded by the Betic fold mountain chain.
This paper presents the study of four sections recording the OAE1a in Spain, from two different basins (Southern Iberian Palaeomargin and North Cantabrian Basin, Fig. 1), and also representing...

The Iberian Peninsula or Iberia (Fig. 1.1) has a total extent of 583,832 km2 encompassing continental Spain and Portugal, the Principality of Andorra, the British colony of Gibraltar and some areas of France in the Pyrenees. To this area, we add the 4992 km2 of the Balearic Islands, which are related to the Iberian Peninsula as they form part of th...
Iberia is a highly diverse territory from the geological point of view, in terms of rock types and relief models, with materials of a long array of ages. Essentially, Iberia was constructed around a primary old core to which successive portions were added in the course of time. This evolution can be divided into several periods, some of them corres...
In this part some more details are given about the main structural units in which Iberia can be divided (Loidi 1999). They are ordered according to their relation to the Meseta or Hesperian Shield, the basement of the Iberian Peninsula (Figs. 1.1 and 1.2).
This basin is concealed in the triangle formed by the Pyrenees, the Iberian System and the Catalan Coastal Ranges, thus forming a closed-to-the-sea basin. It occupies a vast area in the northeastern part of the Peninsula and sediments are lacustrine continental largely due to the circumstance that this basin became endorrheic during a long time bet...
Between the Sierra Morena and the Baetic Ranges there is this sedimentary basin that is open to the Atlantic; it has been filled with recent marine deposits, rich in clay, eroded from the surrounding massifs. Due to their high content of expansible clay, these terrains support an intensive and highly productive cereal agriculture.
At the western end of the Iberian Peninsula a particular sedimentary basin, open to the Atlantic, lies between the westernmost reliefs of both the Central Range and the Sierra Morena ensemble. The northern limits are the calcareous massifs of the Serras de Montejunto and Candeeiros, the western part ends at the Serra de São Mamede, while the Serras...

The geology of the Iberian Peninsula consists of the study of the rock formations on the Iberian Peninsula, which includes Spain, Portugal, Andorra, and Gibraltar. The peninsula contains rocks from every geological period from the Ediacaran to the Quaternary, and many types of rock are represented.
This book provides an updated review of the geology of Iberia, which has played a pivotal role in the geodynamic evolution of the Gondwanan, Rheic, Pangea, Tethys and Eurasian plates over the last 600 Ma, including seismicity and active faulting as well as the modern landscapes in the region.
