![Simplified tectonic reconstruction for lower Jurassic to lower Cretaceous times, showing the intra–Nevado-Filabride and intra-Alpujarride rifts. We suggest that the former, with the External Zones of the Betic Cordilleras (prebetic and subbetic), was related to the Iberian paleomargin, while the latter could be associated with the (Maghrebian) seaway connecting the Neotethys and Atlantic oceans. Note the position of the Subbetic Ridge, the Ojen nappe, and the Ronda peridotites. The continental domain bounded by the intra–Nevado-Filabride and intra-Alpujarride rifts is the so-called Alkapeca block, formed by the Alboran, Kabylia, Peloritania, and Calabria belts. No scale in the sketch.]()
![Inferred Early Miocene tectonic setting of the western Betic Cordillera at c. 19 Ma. The coeval occurrence of the following should be noted: (1) foreland-directed thrusting of the Ronda peridotites on top of the Nieves Unit and development of regional overturned syncline (cored by the late Aquitanian Nava Breccia Fm) in the footwall succession; (2) left-lateral shear between the peridotites and the eclogites of the Ojen Unit; (3) top-to-the-hinterland shear along the upper peridotite boundary; (4) synorogenic extension affecting the upper structural levels of the overriding plate. Here, strongly subsiding basins are being formed and rapidly filled with sediments eroded from nearby areas of high relief raised above base level, thereby producing significant Burdigalian sediment accumulations (Viñuela Group).]()
