Description

The additional tables S1 to S5 show the biostratigraphy and the quantitative analyses carried out on calcareous nannofossils from three stratigraphic sections sampled in the Tanger-Al Manzla area (“Flysch Basin” of northern Morocco): Dar Zhirou, Saf Lahmame, and Seguedla sections. The micropaleontologic analyses were performed at the Laboratory of Stratigraphy of Roma Tre University, from January 2017 to July 2019. Details on the methods followed to perform the analyses are reported in section “3. Material and Methods” of the main text of the paper. The micropaleontologic analyses allowed to distinguish autochthonous and reworked species of calcareous nannofossils. These analyses led to the recognition of the marker species and to the definition of the nannofossils assemblages characterizing the Dar Zhirou, Saf Lahmame, and Seguedla sections. The field work and the micropaleontologic analyses carried out on the study sections allow us to refer them to a Late Miocene (Tortonian-Messinian) wedge-top basin: the Tanger-Al Manzla Basin. Table S6 shows the ichnofacies recognized into the sedimentary successions of the Dar Zhirou, Saf Lahmame, and Seguedla sections, which allow us to indicate the mud-dominated successions of the Tanger-Al Manzla Basin as deposited in a deep-marine environment. The additional Table S7 shows the migration and the migration rates of the Western Mediterranean subduction-related orogen in the last 23 Myr. Table S8 compares the migration and the migration rates of the leading edge of the central Apennines and Rif Chain during the last 18 Myr.
