“…Cycles of alternating sheet and channelized flow demonstrated that the autogenic process was significantly periodic. In the natural environment, a large number of similar fan delta could be identified along the shoreline of basins in arid or semiarid climate (Van Dijk et al 2009;Jia et al 2016Jia et al , 2018. In contrast, the river-dominated delta presented in this paper was simulated using cohesive sediment and constant relative base level.…”

“…There are a number of controlling factors that govern the depositional processes and the internal architecture of a sedimentary system including water and sediment supply, climatic changes, base-level variation, tectonic activities, and so on (Gong et al 2016;Jia et al 2018;Jia et al 2016;Ventra et al 2018;Zhao et al 2018a;Zhao et al 2018b). In order to clarify the controlling mechanism of each factor on the sedimentary system, Beerbower (1964) first classified the above factors into two types, including within-basin and extra-basin factors.…”

Sedimentary characteristics and internal architecture of a river-dominated delta controlled by autogenic process: implications from a flume tank experiment

Autogenic processes are widely found in various sedimentary systems and they play an important role in the depositional evolution and corresponding sedimentary architecture. However, autogenic processes are often affected by changing allogenic factors and are difficult to be identified and analyzed from modern and ancient records. Through the flume tank experiment under constant boundary conditions, the depositional process, evolution principles, and the sedimentary architecture of a river-dominated delta was presented, and a corresponding sedimentary architecture model was constructed. The evolution of river-dominated delta controlled only by autogenic process is obviously periodic, and each autogenic cycle can be divided into an initial progradational stage, a middle retrogratational stage, and a late aggradational–progradational stage. In the initial progradational stage, one feeder channel incised into the delta plain, mouth bar(s) was formed in front of the channel mouth, and small-scale crevasse splays were formed on the delta plain. In the middle retrogradational stage, the feeder channel was blocked by the mouth bar(s) which grew out of water at the end of the initial stage, and a set of large-scale distributary splay complexes were formed on the delta plain. These distributary splay complexes were retrogradationally overlapped due to the continuous migration of the bifurcation point of the feeder channel. In the late aggradational–progradational stage, the feeder channel branched into several radial distributary channels, overlapped distributary channels were formed on the delta plain, and terminal lobe complexes were formed at the end of distributary channels. The three sedimentary layers formed in the three stages constituted an autogenic succession. The experimental delta consisted of six autogenic depositional successions. Dynamic allocation of accommodation space and the following adaptive sediments filling were the two main driving factors of the autogenic evolution of deltas.

“…Under non‐volcanic conditions, clastic sediment supply is controlled by: (i) the tectonically‐induced relief; and (ii) the climatic conditions that produced the mechanical and chemical disaggregation of the rocks exposed in the source areas (Blaine Cecil, ; Catuneanu et al ., ). Transport and settling of particles are subject to the hydrodynamics of the water streams along their drainage networks down to their final depositional settings in water bodies, controlling the progradation/retrogradation arrangement of clastic sequences (Miall, ; Allen, ; Jia et al ., ). Some types of deposit (for example, lithofacies L1 and Sh1 – limestones and palaeosols, respectively) or discontinuities (for example, palaeo‐valley development) may indicate that the clastic ‘source to sink’ system is not able to sustain the sediment supply (cf.…”

This work focuses on the transition from the Las Leoneras to Lonco Trapial Formations, in the lower part of the Early Jurassic succession of the incipient rift phase of the Cañadon Asfalto Basin (western part of Chubut Province -Patagonia, Argentina). Twenty lithofacies have been identified and grouped into seven facies associations on the basis of field characteristics (sedimentological and lithological) and optical microscope analysis, from two localities representing proximal and distal locations in the basin. The spatial relationship between all the lithofacies provided a four-dimensional reconstruction of the palaeoenvironmental evolution, showing how the original, clastic sedimentation in alluvial/fluvial and lake environments was modified by shortlived volcanic events during three volcanic cycles, and how the environment reacted after the input of huge amounts of volcaniclastics. Progradation of small deltas and subaqueous lobes, retrogradation caused by rising lake levels, and frequent erosion of valleys were typical processes in this environment. When explosive volcanism began, the original tectono-climatic control on sedimentation was replaced by the volcanic control, and the volcanicallyforced sedimentation broke the equilibrium among production, delivery and accumulation of sediments. The nature of the volcanic eruptions and the different propensity of volcanic lithofacies to produce particles of different size and types (lithics, crystals and glass) are also analyzed. The role of volcanism in the production and transport of great volumes of sediments across sedimentary systems needs to be carefully re-examined, and the analysis on the variability in the composition of volcaniclastic deposits must take into account that volcaniclastic particle types may not simply reflect a linear deepening in the dissection of magmatic arcs through time but are often controlled by the style of the eruptions and the lithological variation of the volcanic products.

“…As a result, frequent lacustrine fluctuations contain potential influences on the retrogradation and progradation of depositional systems (Allen & Allen, 2013). Previous studies indicate that palaeoclimate changes from arid conditions in the Early Triassic to humid conditions in the Late Triassic Jia et al, 2018;Kuang et al, 2017). In the Early Baikouquan Formation (T 1 b 1 ), arid climate results in falling of lake level which assists in the progradation of fan delta systems.…”

The depositional evolution and controlling factors of the Lower Triassic Baikouquan Formation, Northern Mahu Slope, Junggar Basin, NW China

Baikouquan Formation have been found in the last few years in Mahu Sag, Junggar Basin. Many studies have been conducted to describe the sedimentological complexity of reservoirs. However, few of them have been focused on the depositional characteristics and associated controlling factors in Baikouquan Formation. In this study, analysis of cores, thin sections, wireline logs, and seismic volume were carried out obtain detailed descriptions and interpretations of sedimentary microfacies, depositional evolution, and associated controlling factors. The results indicate that seven sedimentary microfacies are identified in Baikouquan Formation. Furthermore, depositional evolution of fan delta systems from bottom to top of Baikouquan Formation shows retrogradation in general. Tectonic activities along the northwestern fault zone, rising lake levels, arid climate, and high temperature together exert the controls on depositional evolution of fan delta systems in Baikouquan Formation.
