Résumé

This chapter summarises the key points addressed in the previous four. From the K–T boundary to the present, the Pyrenees as a mountain range rising between Europe and Iberia went through three successive states: the proto-Pyrenees, the ancestral Pyrenees, and the modern Pyrenees. Throughout this period, the mountain range changed in length, width, relief and elevation. The proto-Pyrenees began to emerge in the east, forming a mountain range that coincided with the eastern third of the modern Pyrenees. Mountain topography extended at the time farther east into the area now occupied by the Gulf of Lion. Growth of the mountain belt extended westward from Ypresian time and the ancestral Pyrenees appear to have attained their peak energy and peak topography between the Priabonian and the Oligocene, at a time when the Ebro Basin was entering its ~20–25-million-year period of internally drained sedimentary confinement. Mountain-front fan systems became ubiquitous on both sides of the orogen during this time interval. The chapter delivers a comparative analysis of the depositional histories in the pro- and retro-foreland basins of the orogen. Explanations to a number of recorded features are contained among the rich assemblage of geomorphological and chronostratigraphic evidence encountered in the elevated massifs and Neogene extensional basins of the eastern Pyrenees, which are explored in greater depth throughout the nine itineraries described in chapters 6 to 14 of this GeoGuide.
