Geochemistry of Fluvial Sediments from Geregu, Southwest Nigeria

“…In a previous study, it has been suggested that sediments have ultramafic igneous rock source when the Cr and Ni contents are >150 ppm and >100 ppm, respectively [46]. Elevated contents of Cr and Ni in sediments have also been used to infer an ultramafic source composition by previous workers [11,28,47,48,49]. According to Armstrong-Altrin et al [28], the increase in Cr and Ni contents from Playa-Azul to Teculutla to Nautla sands, which corresponds to an increasing order in the Cr/ Ni ratios, represents a more mafic source rock composition for the Nautla sand as compared with the other sands on the western Gulf of Mexico beach.…”

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.…”
