Defining the concept of stratigraphic grade and applying it to stratal (reservoir) architecture and evolution of the slope-to-basin profile: An outcrop perspective

Sedimentation styles and depositional processes in a Middle to Late Jurassic slope environment, Bowser Basin, northwestern British Columbia, Canada

“…This evolution towards a graded depositional profile (cf. Ross et al, 1994;Pyles et al, 2011) is consistent with normal progradation of the slope system, in which gravity flow processes are in equilibrium with sediment supply, basin subsidence, and basin physiography, and does not require the influence of tectonic input.…”

Depositional architecture and sequence stratigraphy of the Karoo basin floor to shelf edge succession, Laingsburg depocentre, South Africa

“…These include the Eocene basin of Svalbard (Steel et al, 2000(Steel et al, , 2003, the Brushy Canyon area of West Texas (Beaubouef et al, 1999;Gardner et al, 2003), the Carboniferous of western Ireland (Pyles, 2008;Pyles et al, 2011), the Miocene Marnoso-Arenacea of Italy (Tinterri and Magalhaes, 2011) and the Cretaceous Magallanes Basin of southern Chile (Romans et al, 2011). This paper presents for the first time a synthesis of the complete stratigraphic section of the Ecca Group (Permian) of the Laingsburg Karoo area, South Africa ( Fig.…”

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).…”
