“…Based on the gradually but irregularly rising shelf-edge trajectory, an overall water 638 depth increase from ~ 250 to > 400 m is recorded. Subsidence was directly linked to Laramide 639 tectonic activity across the region, triggering subsidence in the basin and uplift in its source area 640 (Carvajal 2007;Carvajal and Steel 2012). Stage 2, represented by clinothems C10-15, began when 641 active thrusting and uplift in the source area had decreased or ceased (Carvajal 2007).…”

“…The average sediment supply rate calculated for Stage 1 is ~ 4 -10 * 10 6 ton / yr; the 645 progradational succession of Stage 2 has a higher sediment supply rate of 8 -16 * 10 6 ton / yr during 646 a period of tectonic inactivity (Carvajal 2007, Carvajal andSteel 2012). The increase in sediment 647 supply from Stage 1 to Stage 2 is counterintuitive since the decreasing rate of thrusting in the source 648 area is expected to correspond to a decrease in the sediment yield.…”

“…The increase in sediment 647 supply from Stage 1 to Stage 2 is counterintuitive since the decreasing rate of thrusting in the source 648 area is expected to correspond to a decrease in the sediment yield. The increase in sediment yield is 649 therefore linked to modest uplift due to isostatic rebound, persistence of high relief, and increasing 650 catchment area (Carvajal 2007;Carvajal and Steel 2012). Additionally, the overall sand/shale ratio 651 increases over time, which has been ascribed to erosion of increasingly sandy source rock, 652…”

1Progradational fluvio-deltaic systems tend towards but cannot reach equilibrium, a state in 2 which the longitudinal profile does not change shape and all sediment is bypassed beyond the 3 shoreline. They cannot reach equilibrium because progradation of the shoreline requires 4 aggradation along the longitudinal profile. Therefore progradation provides a negative feedback, 5 unless relative sea level falls at a sufficient rate to cause non-aggradational extension of the 6 longitudinal profile. How closely fluvio-deltaic systems approach equilibrium is dependent on their 7 progradation rate, which is controlled by water depth and downstream allogenic controls, and 8 governs sediment partitioning between the fluvial, deltaic, and marine domains. Here, six analogue 9 models of coastal fluvio-deltaic systems and small prograding shelf margins are examined to better 10 understand the effect of water depth, subsidence, and relative sea-level variations upon longitudinal 11 patterns of sediment partitioning and grain-size distribution that eventually determine large-scale 12 stratigraphic architecture. Fluvio-deltaic systems prograding in relatively deep-water environments 13 are characterized by relatively low progradation rates compared to shallow-water systems. This 14 allows these deeper water systems to approach equilibrium more closely, enabling them to 15 construct less concave and steeper longitudinal profiles that provide low accommodation to fluvial 16 systems. Glacio-eustatic sea-level variations and subsidence modulate the effects of water depth on 17 the longitudinal profile. Systems are closest to equilibrium during falling relative sea level and early 18 lowstand, resulting in efficient sediment transport towards the shoreline at those times. 19Additionally, the strength of the response to relative sea-level fall differs dependent on water depth. 20In systems prograding into deep water, relative sea-level fall causes higher sediment bypass rates 21 and generates significantly stronger erosion than in shallow-water systems, which increases the 22 probability of incised-valley formation. Water depth in the receiving basin thus forms a first-order 23 control on the sediment partitioning along the longitudinal profile of fluvio-deltaic systems and the 24 shelf clinoform style. It also forms a control on the availability of sand-grade sediment at the 25 3 shoreline that can potentially be remobilized and redistributed into deeper marine environments. 26

“…However, recent outcrop studies demonstrate that the construction of sediment volume or mass budgets within the source-to-sink context of a sediment routing system can provide a powerful tool to quantitatively estimate the volume and grain size of sediment supply (e.g. Duller et al 2010;Whittaker et al 2011;Carvajal & Steel 2012;Michael et al 2013). The results are particularly useful if analysed in a mass-balance framework, in which the cumulative deposited volume of sediment in the downsystem direction is normalized by the total sediment volume (e.g.…”

Towards a sequence stratigraphic solution set for autogenic processes and allogenic controls: Upper Cretaceous strata, Book Cliffs, Utah, USA

Upper Cretaceous strata exposed in the Book Cliffs of east-central Utah are widely used as an archetype for the sequence stratigraphy of marginal-marine and shallow-marine deposits. Their stratal architectures are classically interpreted in terms of accommodation controls that were external to the sediment routing system (allogenic), and that forced the formation of flooding surfaces, sequence boundaries, and parasequence and parasequence-set stacking patterns. Processes internal to the sediment routing system (autogenic) and allogenic sediment supply controls provide alternatives that can plausibly explain aspects of the stratal architecture, including the following: (1) switching of wave-dominated delta lobes, expressed by the internal architecture of parasequences; (2) river avulsion, expressed by the internal architecture of multistorey fluvial sandbodies and related deposits; (3) avulsion-generated clustering of fluvial sandbodies in delta plain strata; (4) 'autoretreat' owing to increasing sediment storage on the delta plain as it lengthened during progradation, expressed by progradational-toaggradational stacking of parasequences; (5) sediment supply control on the stacking of, and sediment grain-size fractionation within, parasequence sets. The various potential allogenic controls and autogenic processes are combined to form a sequence stratigraphic solution set. This approach avoids anchoring of sequence stratigraphic interpretations on a specific control and acknowledges the non-unique origin of stratal architectures.

Sedimentology of the deltaic Paleogene Shahejie Formation in the D‐1 area of Liaodong Bay, East China

The Liaodong Bay area in northeast China has abundant hydrocarbon resources. The study area (referred to as D-1) is located in the southeast portion of the Liaodong Graben, a tectonic unit of Liaodong Bay, where the focus for exploration is on sandstone units in the Palaeogene Shahejie Formation. Here, hydrocarbons with an oil production capacity of 629 m 3 /day have been discovered in well D-1-2SA. The reservoir facies have been analysed by combining the cuttings, logging, seismic data, sedimentary facies, and sequence stratigraphy. In the sequence stratigraphic study, the second member from the base of the formation is divided into one third-and four fourth-order depositional sequences. The sedimentary facies include fan deltaic, braided river deltaic, and lagoonal systems. Seismic attribute inversion of the sequence framework, depositional models, and sediment distribution has been conducted for each system tract. The reservoirs facies in the D-1 area are characterized by medium to low porosity, and medium to low permeability. The development of reservoirs facies is related to the subaqueous depositional channels of the fan deltaic system with the best quality for hydrocarbon storage. These channels have strong root mean square amplitudes used for seismic attribute identification for reservoir targets. The formations of the source-to-sink system with granitic and metamorphic source rocks and relative distant transportation are considered to have the best potential for hydrocarbon reservoirs.
