Triassic redbeds in the Malaguide Complex (Betic Cordillera — Spain): Petrography, geochemistry and geodynamic implications

Sedimentological and Geochemical Composition of Aeolian Sediments in the Taklamakan Desert: Implications for Provenance and Sediment Supply Mechanisms

“…The chemical composition of clastic sediments is the combined result of the source rock composition and chemical weathering processes (Perri et al, ; Sawyer, ). Nesbitt et al () demonstrate that the chemical composition of mobile elements of sediments may not reflect provenance directly because of the effects of chemical weathering.…”

“…The chemical composition of sediments changes through three principal processes: weathering of the source rocks, sorting, and, in some cases, recycling (Perri et al, ; Sawyer, ). Weathering of the source rocks typically occurs in the source area through pedogenesis and diagenesis and less frequently during subsequent transportation (Sawyer, ).…”

The Early Miocene “Bisciaro volcaniclastic event” (northern Apennines, Italy): a key study for the geodynamic evolution of the central-western Mediterranean

“…Towards the west, the oceanic Calvana-Lucania Basin (see later) was separated the Adria continental margin by a continental Microplate (Mesomediterranean Microplate; Guerrera et al 2005; cum bibl.). According to Critelli et al (2008) and Perri et al (2013), the western Mediterranean palaeogeography during the MiddleLate Trias-Early Cretaceous foreshadowed the birth of this intermediate microplate (see also Doglioni 1992). …”

Tectonic evolution of the Sicilian Maghrebian Chain inferred from stratigraphic and petrographic evidences of Lower Cretaceous and Oligocene flysch

“…The sedimentary succession of these internal sectors (the so-called "Dorsale Calcaire", sensu Fallot 1937) is almost the same along all the western peri-Mediterranean chains, between the Gibraltar and Calabria-Peloritani Arcs. The Rifian "Dorsale Calcaire" is often marked by a pronounced discontinuity because its Mesozoic portion (Triassic-Liassic Verrucano-like redbeds evolving to Lower Jurassic platform carbonates; Perrone et al 2006;Critelli et al 2008;Zaghloul et al 2009;Perri et al 2011Perri et al , 2013, related to the Tethyan rifting, usually lacks post-Toarcian to Upper Cretaceous deposits (Chalouan et al 2008) and, locally, it is topped by Eocene detrital Nummulitic limestones (Nold et al 1981;El Kadiri et al 2006), representing a depositional sequence post-dating an early Alpine compressive event (Maate 1996;Martin-Algarra et al 2000). Unconformable Oligocene turbidite deposits locally characterize the top of the succession (Olivier 1979;Durand-Delga & Fontboté 1980;Wildi 1983;Zaghloul et al 2005;Puglisi 2008); 2.…”

“…Also in the Sicilian Maghrebian Chain, the sedimentary cover of the Lower Cretaceous flysch is almost always absent. Locally, very few outcrops of thin and discontinuous upper Cretaceous-to-Paleocene successions are present and doubtfully interpreted as a possible sedimentary cover (Cassola et al 1990;Puglisi 1992Puglisi , 1998; Finally, the above mentioned Hercynian crystalline units of the Betic-Maghrebian Chain, tectonically overlying the Lower Cretaceous flysch, belong to the so-called AlKaPeCa block (sensu Bouillin et al 1986), which includes the Alboran, Kabylides and Peloritani + Calabria terranes, originally located in the southern Iberian paleomargin, according to many authors (Biju-Duval et al 1977;Stampfli et al 1998;Sanz de Galdeano et al 2001;Rosenbaum et al 2002;Mauffret et al 2004;Schettino & Turco 2006;Perrone et al 2006;Critelli et al 2008;Perri et al 2013). …”
