“…Furthermore, the interbeds of reddish and grey sandstone are interpreted as intermittent exposure related to the lake‐level change (Figure d). Thus, these features are similar to some previous geological records in the foreshore setting (Benyoucef & Meister, ; El‐Azabi & El‐Araby, ; Zecchin & Caffau, ).…”

“…Furthermore, the interbeds of reddish and grey sandstone are interpreted as intermittent exposure related to the lake-level change(Figure 5d). Thus, these features are similar to some previous geological records in the foreshore setting(Benyoucef & Meister, 2015;El-Azabi & El-Araby, 2007;Zecchin & Caffau, 2011).Second, the possible interpretation for the deposition of FA3 and FA4 is shoreface environment. The identified marks include (a) decreased clastic content of coarse-grained sand in both FA4 and FA5; (b) presence of oolitic deposits.…”

Mixed siliciclastic–carbonate sediments were well developed in the BZ‐X block as a subunit in the Huanghekou Sag in the southeastern part of the Bohai Bay Basin (China) during the Member 1 of the Shahejie Formation. An integrated approach based on detailed microscopic observation and core descriptions was applied to characterize the lithofacies types, facies associations, and depositional environment of the mixed sediments system. A detailed sedimentary facies analysis suggests that various lithofacies types can be grouped into four facies associations: mixed bioclastic sandy beaches (FA1), mixed clastic bioclastic shoal (FA2), mixed sandy oolitic shoals (FA3), and mixed distal bioclastic sandy beaches (FA4). These facies associations are interpreted to be deposited in varying depositional environments ranging from foreshore to shoreface setting in a shallow lake setting. An interplay of the climate regime, nearshore carbonate productivity, and current activity was proved to control the lithofacies types, dispersion and depositional environment change of mixed sediments in different depositional phases. Meter‐scale mixed cycles were found in this shallow lake setting and their features seem to differ from the classical mixed sediment models. It is suggested that these particular cycles in the stratigraphic record might indicate a typical mark of mixed sediment system in shallow areas of the lacustrine basin.

“…Low-angle stratification, the well sorted nature of the sandstones together with rounded grain outlines also indicate a beach-type depositional setting (c.f. Nichols, 2000), as do wave ripples and horizontal lamination (El-Azabi and El- Araby, 2007). Red siltstones and mudstones and thin fining-upward cycles can be interpreted in terms of of flood plain deposition.…”

Upper Jurassic carbonates of the Mozduran Formation constitute the principal reservoir intervals at the giant Khangiran and Gonbadli gasfields in the Kopet Dagh Basin, NE Iran. These carbonates were investigated using detailed field studies and petrographic and wireline log analyses in order to clarify their depositional facies and sequence stratigraphy. Facies were interpreted to reflect deep basin, fore-shoal, shelf margin, lagoon, tidal flat and coastal plain depositional systems.The Mozduran Formation is composed of six depositional sequences. Thickness variations were controlled by differential subsidence. Aggradation on the platform margin and reduced carbonate production in the deep basin together with differential subsidence resulted in the creation of a narrow seaway during the late Oxfordian. Petrographic studies suggest that Mozduran Formation carbonates had a low-Mg calcite mineralogy during the Oxfordian, and an aragonite to high-Mg calcite mineralogy during the Kimmeridgian. Reservoir pay zones are located in highstand systems tracts within the lower and middle Kimmeridgian depositional sequences. The rapid lateral thickness variations of these sequences were controlled by tectonic factors, leading to compartmentalization of the Mozduran Formation reservoir with the possible creation of stratigraphic traps, especially at the Khangiran field.

“…These facies associations are recorded only from the uppermost Shueib Formation in central and south Jordan or as coeval lateral facies changes of the Buttum Formation in North Sinai, Egypt which consist of much reduced thicknesses of regressive siliciclastic sabkha/shale unit. A rapid fall in sea level in late Turonian to early Coniacian time resulted in a depositional hiatus (possibly from early to mid-Coniacian) that can be traced as a major sequence boundary throughout the African/Arabian plate (Sharland et al, 2001;Haq and Al-Qahtani, 2005;El-Azabi and El-Araby, 2007;Powell andMoh'd, 2011, Farouk andFaris, 2012), but shows no correspondence to the eustatic sea-level curve and is represented by a significant maximum flooding event near the Turonian-Coniacian boundary (Haq, 2014;Hardenbol, et al, 1998).…”
