“…Gravity flows in the deep-lacustrine environment can lead to deposition of sediments with similar sedimentological characteristics as the deep-marine counterpart (Mulder et al 2003;Meiburg and Kneller 2010). Depositional elements of deep-lacustrine deposition include slump, channel, levee and lobes (Zhang and Scholz 2015), which are similar to the well-acknowledged deepmarine deposition (e.g. Posamentier and Kolla 2003).…”

Meanwhile, a tremendous amount of petroleum has been exploited from clastic reservoirs accumulated by deep-lacustrine gravity flows in China.…”

Deep-marine and deep-lacustrine reservoirs have been targets for conventional and unconventional oil and gas exploration and development for decades. Thickening-upward cycles in the deep-marine Carboniferous Ross Sandstone Formation outcrops in western Ireland and the deep-lacustrine Triassic Yanchang Formation outcrops in southeast Ordos Basin have been investigated and correlated in this study. Typical thickening-upward cycles consisting of, from bottom to top: (1) laminated shales/shales with interbedded siltstone beds; (2) interbedded sandstones/siltstones and mudstones; (3) structureless massive sandstones, are well recognized in these outcrops and are interpreted as turbidite lobes. A continuously prograding lobe-element model is proposed to explain the repeated stacking of thickening-upward cycles. Thickening-upward cycles developed within deep-marine and deeplacustrine environments are highly comparable in many aspects, such as sedimentary structures, sheet-like geometries and amalgamation features. A frequent and strong degree of amalgamation is developed within the massive sandstone at the top of each thickening-upward cycle, suggesting a layer-by-layer depositional manner. Field observations and comparison with deep-marine counterparts support the occurrence of turbidity flows in the Yanchang Formation, Ordos Basin.

“…Based on the facies association distribution and their controls on reservoir connectivity and quality, it can be concluded that the middle and upper parts of the T 1 b 2 2-3 medium-term cycle have the highest reservoir quality and hydrocarbon potential, which can also be evidenced by the oil layer distribution (Figure 2 (Zhang & Scholz, 2015). However, their detailed characteristics and driving mechanisms remain far from understood.…”

Both sedimentology and sequence stratigraphy variability in the deltaic area are distinguished in the fan‐delta system of the Northwestern Junggar Basin. Sediment supply plays a significant role in controlling the fan‐delta petrology, evolution, and depositional processes and the delivery of sediment into deeper parts of the basin. The results of this study show that variations in the lithology of the sediment supply control the fan‐delta petrology and spatial and temporal variations in sediment supply influence the location and shifting of depocentres. A fining‐upward fan‐delta succession developed as accommodation rates outpaced the sediment supply rate. Frequent flood events were mostly recorded by sediment gravity flow deposits, which in turn influenced the geometry of the sandstone bodies and their reservoir quality. Hyperpycnal flow was a significant delta front process and an important mechanism for sediment delivery into deeper waters, favoured by the combination of denudation of coastal ranges and the fresh waters of the receiving basin. This study highlights that a detailed understanding of variations in sediment supply is essential to accurately predict sediment partitions in a delta system and the delivery of coarse‐grained sediments into deeper parts of lacustrine basins.
