Sedimentary heterogeneity and petrophysical characterization of Barremian tsunami and barrier island/inlet deposits: The Aliaga outcrop as a reservoir analogue (Galve sub-basin, eastern Spain)

“…A comparison of the characteristics of the studied b.i./inlet deposit with the Upper Cretaceous outcrop of inlet deposits associated to barrier-island described by Jackson and Rawn-Schatzinger (1993) shows similarities in the distribution and lithology of facies (Table 9) over a similar distance of 165 meters. The distribution and lithology of facies is related to lateral migration of the tidal inlets and their tidal energy flux, sand sources and channel configuration (Jackson and Rawn-Schatzinger, 1993). In the North sector of Aliaga outcrop, the studied deposit is composed of sand facies, which are similar to the inlet-infill facies characterized by Jackson and Rawn-Schatzinger (1993).…”

“…tsunami porosity range (14%-22%) but which would be higher in the absence of cementation (Henares et al 2014). In inlet deposits associated with barrier islands, Jackson and Rawn-Schatzinger (1993) observed large amounts of calcite cement in oyster-rich beds.…”

“…The distribution and lithology of facies is related to lateral migration of the tidal inlets and their tidal energy flux, sand sources and channel configuration (Jackson and Rawn-Schatzinger, 1993). In the North sector of Aliaga outcrop, the studied deposit is composed of sand facies, which are similar to the inlet-infill facies characterized by Jackson and Rawn-Schatzinger (1993). The inlet-infill facies consisted of coarser-grained sandstone and more poorly-sorted sandstone than the facies of tidal channel.…”

Sedimentology and Sequence Stratigraphy of Shallow Marine Sediments in a Syn-Rift Setting: Hugin Formation, South Viking Graben

“…The Almond Formation has been subdivided into a lower, alluvial unit and an upper, shallow marine unit which forms the focus of this study (Jacka, 1965;Van Horn, 1979;Sturm et al, 2001 Rock Springs Uplift interpreted previously within the shallow marine Almond Formation including; tidal channel, lagoonal, estuarine, tidal delta, marsh, shoreface and foreshore (e.g. Jacka, 1965;Roehler, 1979;Jackson and Rawn-Schatzinger, 1993;Hendricks, 1994;Schatzinger and Tomutsa, 1999;Caldaro-Baird et al, 2001;Kovach et al, 2001;Martinsen, 2003). The depositional setting for the Almond Formation within the Rock Springs region has typically been interpreted as a N-S trending barrier-bay shoreline with barrier island sandstones interpreted within several stratigraphic intervals (Fig.…”

“…Although syn-depositional structures are documented to influence the deposition of the Almond Formation in the subsurface Washakie Sub-basin and Wamsutter Arch, which lie to the east of the outcrop belt (e.g. Jackson and Rawn-Schatzinger, 1993;Clawson and Fawret, 1997;Krystinik and Mead, 1998), the structural setting during deposition in the region of the Rock Springs Anticline was comparatively simple.…”
