“…Modern analogues to this system, where fluvial-dominated deltas prograde into shallow water basins with a near-horizontal shoreline trajectory, include the modern Burdekin delta (Fielding et al, 2005a) and the Neogene and modern Volga delta (Kroonenberg et al, 1997;Overeem et al, 2003;Hinds et al, 2004;Kroonenberg et al, 2005). These examples contain sharp-based mouth bars and distributary channels that cut into offshore mudstones, similar to some of the Phase II successions.…”

Hightlights:• Core-based sedimentology of Jurassic deltaic strata from offshore Norway• Facies analysis of tide-influenced deltaic and estuarine petroleum reservoirs represented by an overall upward decrease in grain size, decrease in fluvial influence and increase in tidal influence. This evolution is attributed to an allogenic increase in the rate of accommodation space generation relative to sediment supply due to tectonic activity of the rift basin. In addition, during progradation, there was also an autogenic increase in sediment storage on the coastal plain, resulting in a gradual autoretreat of the depositional system. This is manifested in the subsequent aggradation of the system, when coarse-grained sandstones were trapped in proximal locations, while only finer grained sediment reached the coastline, where it was readily reworked by tidal and wave processes.

“…Over 70 km of shallow seismic data were collected, focused on the uppermost 10 m of sediment, and the principal seismic facies types used to characterize sedimentation and stacking patterns (Hoogendoorn et al, 2010). A total of 25 shallow cores were collected, also in 2006, with core localities chosen based on the results of the seismic survey, to give representative coverage of all localities and sediment types Lychagin et al, 1995); (b) geomorphology and physiography (after Lychagin et al, 1995); (c) vegetation (after Labutina et al, 1995;Overeem et al, 2003) and (d) location of seismic surveys, cores and surface samples.…”

Reconstructions of deltaic environments from Holocene palynological records in the Volga delta, northern Caspian Sea

et al. 2014

New palynological and ostracod data are presented from the Holocene Volga delta, obtained from short cores and surface samples collected in the Damchik region, near Astrakhan, Russian Federation in the northern Caspian Sea. Four phases of delta deposition are recognized and constrained by accelerated mass spectrometry (AMS) radiocarbon ages. Palynological records show that erosive channels, dunes (Baer hills) and inter-dune lakes were present during the period 11,500-8900 cal. BP at the time of the Mangyshlak Caspian lowstand. The period 8900-3770 cal. BP was characterized regionally by extensive steppe vegetation, with forest present at times with warmer, more humid climates, and with halophytic and xerophytic vegetation present at times of drought. The period 3770-2080 cal. BP was a time of active delta deposition, with forest or woodland close to the delta, indicating relatively warm and humid climates and variable Caspian Sea levels. From 2080 cal. BP to the present-day, aquatic pollen is frequent in highstand intervals and herbaceous pollen and fungal hyphae frequent in lowstand intervals. Soils and incised valley sediments are associated with the regional Derbent regression and may be time-equivalent with the 'Medieval Warm Period'. Fungal spores are an indicator of erosional or aeolian processes, whereas fungal hyphae are associated with soil formation. Freshwater algae, ostracods and dinocysts indicate mainly freshwater conditions during the Holocene with minor brackish influences. Dinocysts present include Spiniferites cruciformis, Caspidinium rugosum, Impagidinium caspienense and Pterocysta cruciformis, the latter a new record for the Caspian Sea. The Holocene Volga delta is a partial analogue for the much larger oil and gas bearing Mio-Pliocene palaeo-Volga delta.

“…Outcrop and seismic data from multiple studies demonstrate the existence of progradational configurations of most delta-front bodies, whether in marine or lake basins (Overeem et al, 2003;Olariu and Bhattacharya, 2006;Olariu et al, 2010;Turner and Tester, 2006;Jacob et al, 2010;Beate et al, 2010). Based on the type of basin, the gradient of the accumulation surface, and ratio between the rate of generation of accommodation via subsidence and the rate of sediment accumulation on the delta front, sand-body stacking patterns indicative of progradation can take the form of oblique, sigmoid and low-angle shingled arrangements (Berg, 1982;George, 1990).…”

Detailed analysis of the internal architectures of the delta-front bodies records the mechanism of growth of a large-scale, shallow-water delta succession. However, significant differences are identified in the development of this lacustrine delta compared to that of more commonly recognized marine shelf-edge delta systems.Lacustrine subaqueous distributary channels have 3 to 15 m-thick sandstone fills and 2 are more abundant and better developed than their marine counterparts: such channelized bodies are highly elongate and many can be traced several kilometres.Such bodies can be shown to be commonly associated with thin-bedded mouth-bar and subaqueous interdistributary-bay deposition. Overall, the Yanchang Formation is characterized by 4 major transgressive-regressive cycles, the development of which was controlled by a combination of changes in the rate of tectonic subsidence, the rate of sediment delivery from the basin margin hinterland and climate -factors that were themselves influenced by intracontinental growth of the neighbouring Qinling Orogen.
