“…The upward‐fining channelized successions with coarse sediments of F14 are interpreted as tidal channels (Fig. F; Gomez‐Veroiza & Steel, ; van Cappelle et al ., ). This interpretation is further supported by the bidirectional but landward‐dominated palaeocurrents and the occurrence of double mud drapes.…”

“…The shallow water ramp settings and relatively small S2S systems result in deposits that are primarily formed by river, fair‐weather wave and storm processes, commonly with modest tidal influence. Such a depositional setting is ideal for studies that document interactions of mixed depositional processes (Hampson & Storms, ; Yoshida et al ., ; Hampson et al ., ; van Cappelle et al ., ).…”

“…Wave‐dominated deltas and non‐deltaic shorefaces ( sensu fluviatile and non‐fluviatile coastlines of Ainsworth et al ., ) share similar facies characteristics and are not always distinguished from one another, especially given the fact that shoreline protuberance is not a necessity for delta definition (Olsen et al ., ; Hampson & Storms, ; Pontén & Plink‐Björklund, ; Charvin et al ., ; Hein et al ., ; Vakarelov & Ainsworth, ; van Cappelle et al ., ). The distinction may be more difficult where a non‐deltaic shoreface is attached to the sand‐dominated updrift part of an asymmetrical delta (Bhattacharya & Giosan, ) or wave reworking overwhelms river input due to low sediment supply in a wave‐dominated delta (Ainsworth et al ., ).…”

“…Fluvial influence is the key to differentiating wave‐dominated deltas from non‐deltaic shorefaces. Determination of fluvial influence, including quantitative analysis of river proportion and size of ancient systems (Hampson & Howell, ) requires detailed facies analysis, especially of the muddy deposits (Burton et al ., ; van Cappelle et al ., ).…”

Depositional facies have been hypothesized to be linked to sequence stratigraphic positions. Also, shoreline systems are built by mixed processes, including rivers, storms, fair-weather waves and tides. Resolving the complexity of shoreline deposition requires detailed quantitative facies analysis with particular attention to heterolithic successions. In this study, 71 sections in a 130 km long outcrop belt of the Cretaceous Gallup Formation in the north-west of the San Juan Basin were measured. Five major facies associations were identified using sedimentological and iconological interpretations, including offshore shelf, non-deltaic shoreline sandstones, deltas, coastal bayline and fluvial. Each facies association also comprises subordinate facies. Depositional facies interpretations are placed in a high-resolution sequence stratigraphic framework that allows for reconstructions of the palaeogeography of individual parasequence sets that demonstrate temporal and spatial evolution of facies associations and depositional processes. The results show that the Gallup is a mixed-process-controlled depositional system with fair-weather and storm-wave dominance, river influence and tideeffect, contrasting with previous interpretations of a solely fair-weather wave-dominated environment. Depositional processes and the resultant facies change with sequence stratigraphic positions in response to relative sea-level changesparticular facies are only deposited in certain systems tracts. Distinction and transition between non-deltaic shorefaces and wavedominated deltas have also been documented in this study. Non-deltaic shorefaces are characterized by homogeneous sandstones with a wide-range bioturbation index and the absence of mudstones. Wave-dominated deltas are subject to river influence and contain prodelta facies. This study shows the importance of detailed facies analysis with high-resolution sequence stratigraphic control using outcrops for documenting sedimentary processes of shallow marine shoreline systems.

Rocks of coastal to shallow‐marine origin are challenging to interpret owing to the complex interplay of various depositional processes. This study reevaluates the relative roles of fluvial, tidal and wave processes in the Upper Cretaceous Sego Sandstone (and subordinately in the underlying Buck Tongue) of the Book Cliffs, USA, a well‐studied ancient coastal to shallow‐marine succession. Detailed sedimentological and ichnological analyses were used to interpret a previously underemphasised riverine signature, consisting of centimetre‐ to decimetre‐thick alternations of sandstone and heterolithic beds inferred to represent flood‐interflood periods of variable river discharge. Recognition of a widespread fluvial‐dominated signature across the studied units better agrees with other sedimentological and regional observations in the study area, such as high sandstone‐mudstone ratios, largely unidirectional and seaward‐oriented palaeocurrents, and modelled weak tidal conditions in the basin. When considering all of the sedimentological, ichnological and stratigraphic observations together with its regional depositional context, the Sego Sandstone/Buck Tongue system is better explained using a mixed‐energy but fluvial‐dominated deltaic model. This highlights an historical over‐interpretation of tidal processes and subordinate wave processes in the Sego Sandstone and likely in similar units. The widely used approach that emphasises only certain sedimentary features in discerning the process regime from analysis of rocks of inferred coastal to shallow‐marine origin is unrefined and may therefore underrepresent the actual complexity of these systems.

The stratigraphic, spatial and temporal variability of detrital zircon age populations in continental sedimentary successions is a critical tool in understanding palaeodrainage networks and how these systems distributed detritus within sedimentary basins. However, multiple factors, such as variations in sediment‐transport processes, the scale of the depositional environment and the architecture of the sedimentary succession are often overlooked in detrital zircon studies. This article presents detrital zircon U–Pb geochronology from the fluvial‐dominated Colton Formation in the western Uinta Basin (Utah, USA) to assess the system's provenance and evolution. Significant differences in zircon age populations between the Colton Formation and the overlying Green River Formation suggest a reorganisation of the source‐to‐sink system during the transition between the two lithostratigraphic units. Notably, detrital zircon age spectra are not homogeneous across the Colton Formation, therefore physical morphometric parameters were used to verify the possible influence of selective bias during sediment transport. These data reveal that a relatively finer‐grained population of Precambrian, and to a less extent Mesozoic, zircon grains were affected by hydraulic sorting during transport, resulting in a greater relative abundance of older zircon grains in the distal reaches of the distributive fluvial system, whose basinward decrease in competence would have increased the relative proportion of finer zircon fractions in sandstones. Furthermore, there are different trends in the distributions of zircon age populations relative to their stratigraphic position, highlighting the complex architecture of the fluvial palaeo‐fan. The spatial and stratigraphic variability of provenance signals in fluvial‐fan successions must be carefully evaluated to improve the reliability of source‐to‐sink models and palaeodrainage reconstructions, as autogenically controlled noise can be generated during the dispersal of detrital zircon in fluvial sedimentary systems.
