Mineralogical assemblages, geochemistry and fossil associations of Pleistocene–Holocene complex siliciclastic deposits from the Southwestern Doñana National Park (SW Spain): A palaeoenvironmental approach

New sedimentary and geomorphic evidence of tsunami flooding related to an older events along the Tangier-Asilah coastal plain, Morocco

“…Erosion of the substratum by the tsunami flood waters is attested by scour-and-fill features and rip-up clasts (of soil for example). Rip-up clasts of clay or soil (from the substratum or mud lines) grade into stretched rip-ups, discontinuous laminae (Gutiérrez-Mas et al 2009;Pozo et al 2010). The abundance of rip-up clasts of organic matter decreases upwards.…”

The role of neo-tectonics in the sedimentary infilling and geomorphological evolution of the Guadalquivir estuary (Gulf of Cadiz, SW Spain) during the Holocene

“…Later, as revealed by overlying deposits in the cores, a more confined environment became established, increasingly closed to direct tidal ingress and washover yet open to freshwater inflows from the opposite direction. This evolution has been recognized elsewhere in the estuary by means of the paleontological analysis of other cores (Zazo et al, 1999a;Ruiz et al, 2005;Pozo et al, 2010). …”

“…The presence in the PHMF deposits at these locations of burrowing, roots, carbonate nodules and intense lamination suggests either an emerged environment or an environment in transition-subject to periodic tidal inundation as well as freshwater inputs-that the microfauna (Pozo et al, 2010) as well as the pollen (Zazo et al, 1999a) have indicated.…”

“…Significant contributions have only been a fragmentary analysis of a long core (Zazo et al, 1999a;Lario et al, 2001;Pozo et al, 2010) and research on the period between the Upper Pliocene and the Quaternary which has failed to concentrate on the evolution during the Holocene (Salvany et al, 2011).…”

Imprints of historical pollution and the 218-60 BCE tsunamigenic period in southwestern Spain

“…Some of them have presented a review of the associated sedimentary deposits, its main features, and the dynamic processes involved in their formation (Dawson and Steward, 2007;Engel and Brückner, 2011). Others have focused on their sedimentary characteristics (Putra, 2018), their palaeontological record (Mamo et al, 2009;Ruiz et al, 2010) or their mineralogy (Pozo et al, 2010;Costa et al, 2015).…”
