A. Appendix Eocene 54 Ma 42 Ma 36 Ma Oligocene 30 Ma 27 Ma 24 Ma Fig. A.1.: Geological evolution of the Iberian Peninsula in terms of past and present-day stress fields; figures and related description from Andeweg [2002] - this Figure is continued on the next page (Fig. A.2). Main tectonic events relevant for the Iberian Peninsula for the period displayed by this figure: uplift of the Hesperic Massif (basement in western and Central Iberia) due to ENE-WSW extension with perpendicular compression, before that only the western part of the present Iberian Peninsula was emerged (54 Ma); the southern margin of the Iberian Peninsula deepens southward, thrust loading of the margin by Internal Betic units is likely (42 Ma); Uplift of the Spanish Central System (SCS) (36 Ma); Internal Betics crustal segments are stacking, resulting in an over-thickening and subsequent extensional deformation of the Internal Betics (36 Ma); inversion of the Iberian Basin starts (30 Ma); first uplift of the Sierra Altomira (24 Ma). 288

Main tectonic events relevant for the Iberian Peninsula for the period displayed by this figures: onset of collision between the Betics and the southern Iberian margin, resulting in compression and folding in the Eastern Prebetics (21 Ma); elevation of the SCS (15 Ma); collision of the Internal Betics with the southern margin of Iberia, resulting in major inversions throughout the entire Iberian Peninsula (12 Ma); SCS thrusts over Duero and Tajo Basins (12 Ma); thrusting of the Subbetics over the eastern Prebetics and submergence of the western External Prebetics (12 Ma); Uplift of the whole Betics, resulting in withdrawal of the sea and disconnection from marine Mediterranean or Atlantic waters (6 Ma). 289

Main tectonic events relevant for the Iberian Peninsula for the period displayed by this figures: onset of collision between the Betics<br />

and the southern Iberian margin, resulting in compression and folding in the Eastern Prebetics (21 Ma); elevation of the SCS (15 Ma);<br />

collision of the Internal Betics with the southern margin of Iberia, resulting in major inversions throughout the entire Iberian Peninsula<br />

(12 Ma); SCS thrusts over Duero and Tajo Basins (12 Ma); thrusting of the Subbetics over the eastern Prebetics and submergence of<br />

the western External Prebetics (12 Ma); Uplift of the whole Betics, resulting in withdrawal of the sea and disconnection from marine<br />
