The widely debated late Oligocene-middle Miocene Numidian Fm (NF) consists of supermature\u00a0quartzose sediments deposited in the Maghrebian Flysch Basin (MFB) outcropping from the Betic\u00a0Cordillera to the Southern Apennine passing by the Maghrebian Chain. The NF is commonly\u00a0composed of three lithostratigraphic members and is characterized by two vertical successions\u00a0(Type A and Type B) corresponding to different sedimentation areas in the MFB. It is noteworthy the\u00a0occurrence of widespread lateral successions of the NF (Types C, D and E) indicating in some cases\u00a0an interference of the Numidian sedimentation with other different depositional systems and\u00a0supplies. The Type C \u2018Mixed Successions\u2019, deposited in depocentre areas, are composed of supermature\u00a0Numidian supply interfingering with immature siliciclastic materials, coming from the\u00a0internal portion of the MFB. The Type D consists of supermature Numidian materials supplied\u00a0from the Africa Margin (external sub-domains) deposited in sub-basins on the Africa-Adria margins,\u00a0outside the typical Numidian depositional area. The Type E, which stratigraphically overlies both\u00a0the South Iberian Margin (SIM) and the Mesomediterranean Microplate (MM), represents the\u00a0migration of the Numidian depositional system to reach the opposite margins of the MFB. The\u00a0occurrence at a regional scale of all the above-mentioned lateral successions reveals a great\u00a0evolutionary complexity resulting also from further constraints, which must be considered for\u00a0palaeogeographic and palaeotectonic reconstructions. Another important point deals with the\u00a0diachronism of the top of the NF, observed eastward from the Betic-Rifian Arc and the Algerian-Tunisian Tell (Burdigalian p.p.) to Sicily (Langhian p.p.) and up to the Southern Apennine (at least\u00a0Langhian\/Serravallian boundary) which can be related with eastwards delay in the MFB closure.<\/p>\n
