Resumen: | New data reveal Early Burdigalian ‘Numidian-like lithofacies’ in successions of the internal (southernmost) part of the South Iberian Margin (SIM) and the south-western margin of the Mesomediterranean Microplate (MM). The well-known Numidian Formation was deposited in the external (Massylian) sub-domain of the Maghrebian Flysch Basin (a south-western branch of the Tethys Ocean). The anomalous occurrence of ‘Numidian-like lithofacies’ is induced by the particular Early Miocene palaeogeographical and geodynamic complexity of the sector. This consisted of a ‘triple point’ with a dextral transform fault between the SIM and the MM-Maghrebian Flysch Basin system. In this framework, the ageing of Iberian reliefs and the MM collapse, coupled with an African Margin upbulging, and a shortening of the Maghrebian Flysch Basin (both related to the subduction), could have resulted in the arrival of the Numidian depositional system from so far away. |
