Abstract
The rise of the Central System due to reactivation of late
Hercynian fault systems during the Alpine Orogeny directly affected
the strcture and stratigraphic framework of the basins nearby
that were being filled al the same time. The sedimentary record is the
essential key to understanding the tectonic and palaeo-morphological history, of the Central Range, and vice-versa. Relating the filling
of the basins with the definition of the mountain range, pre-arkosic,
arkosic and post-arkosic stages have been proposed. However, it is
difficult to support the previous idea that the arkosic stage continued
throughout the Late Tertiary to finish in Middle Pliocene.:
times withe the deposition of the Paramos(limestone). The arkoscs
of the Central System arc of Eocene-Oligocce age and the highest
alluvial fan deposits may be of Aragonian age. There is only a poor
record of the remaining Tertiary and Quaternary sediments.
