Synsedimentary structural control on foredeep turbidites: An example from Miocene Marnoso-arenacea Formation, Northern Apennines, Italy

Short length-scale variability of hybrid event beds and its applied significance

“…H4 may be absent or may wholly or partly have collapsed into the underlying H3 division. Event beds broadly conforming to the hybrid model have been widely documented in cores from hydrocarbon wells (Haughton et al, 2003Barker et al, 2008;Davis et al, 2009;Kane and Ponten, 2012), shallow sea floor cores (Zeng et al,1991;Talling et al, 2007b;Georgiopoulou et al, 2009;Lee et al, 2013) and outcrops (Wood and Smith, 1959;Mutti et al, 1978;Van Vliet, 1978;Ricci Lucchi and Valmori, 1980;Sylvester and Lowe, 2004;Talling et al, 2004;2007a;2012;Amy and Talling, 2006;Ito, 2008;Hodgson, 2009;Jackson et al, 2009;Muzzi Magalhaes and Tinterri, 2010;Tinterri and Muzzi Magalhaes;2011).…”

“…Entrainment of clasts may occur at various points along the flow path prior to hybrid event bed deposition. It could arise from the erosion of an out-ofgrade slope some distance away , possibly caused by synsedimentary thrusting or other tectonic forcing (Haughton et al, 2009, Tinterri andMuzzi Magalhaes, 2011), or from more local erosion, for example of the mounded tops of previously deposited lobe bodies (Mutti et al, 1977), or channel-lobe transition zones or avulsion nodes where there can be extensive scouring (Mutti andNormark 1987, Wynn et al 2002;Terlaky and Arnott, 2014). The studied event beds are distinct from the matrix-rich and very poorly sorted beds described by Terlaky and Arnott (2014) …”

Evolution of deep-water stratigraphic architecture, Magallanes Basin, Chile

“…The terminal segment of basin-margin sedimentary systems are commonly represented by deep-water turbidites and, as such, preserve relatively complete records of sedimentation, with evidence for variability of external controls in source areas or other segments of the dispersal system (e.g., Normark and Piper, 1991;Einsele et al, 1996;Mutti et al, 2003;Allen, 2008;Covault et al, 2007;Romans et al, 2009a). Documentation of extensive deep-water outcrop belts over the past decade has led to improved understanding of turbidite system architectures and their evolution through time (Gardner et al, 2003(Gardner et al, , 2008Mutti et al, 2003;Hodgson et al, 2006;Pickering and Bayliss, 2009;Flint et al, 2011;Khan and Arnott, 2011;Kane and Hodgson, 2011;Pyles et al, 2011;Tinterri and Muzzi-Magalhaes, 2011).…”

Stratigraphic evolution of a submarine channel–lobe complex system in a narrow fairway within the Magallanes foreland basin, Cerro Toro Formation, southern Chile

“…Basin configuration clearly plays a major role in controlling the stratigraphic evolution and architecture of the deepwater basins. In order to better understand these relationships, detailed, bed-scale observations need to be tied into a larger, depositional system-scale context (see also Flint et al, 2011;Gagnon and Waldon, 2011;Pyles et al, 2011;Romans et al, 2011;Tinterri and Muzzi-Magalhaes, 2011).…”
