“…Dual function of tectonic and sedimentary might lead to different occurrences of adjacent formation, reflecting in differences of seismic reflection characteristics on seismic profiles (Mooney and Brocher, 1987; Gilli et al., 2001; Wang, 2015). For instance, Kumkol formation is of weak amplitude and continuity above the boundary while the Karagansky formation is of strong amplitude and continuity below the boundary (Figure 3(c)).…”

“…Tectonism has a dominant controlling effect on sequence filling of the basin. Specific type and distribution of depositional sequence exists in different stages, especially the early fault activity at the edge of the graben, which has an intense control on the development and distribution of the sequences (Goodbred and Kuehl, 2000; Wang et al., 2015). The sequence thickness has a significant discrepancy in the Jurassic period, later the unified basin pattern formed, and variation in sequence thickness retarded till the stage of Early Cretaceous depression.…”

Jurassic to Cretaceous clastic rocks of the South Turgay Basin were deposited in the typical Mesozoic rift basin formed during the late Triassic collision between the Kazakstan and Siberia plates. In this study, we used more than 140 wells and 2400 km 2 of 3D seismic data in the northern Aryskum Depression to produce a detailed sequence stratigraphic interpretation of the South Turgay Basin. Guided by sequence stratigraphy, sedimentology, and structural geology, lower Jurassic-lower Cretaceous strata of the northern Aryskum Depression in the South Turgay Basin, Kazakhstan were subdivided into 10 third-order sequences based on geological and geophysical data. Combined with tectonic evolution characteristics, sequence developments in the basin can be divided into four stages: early rift stage (SQ1-SQ3), late rift stage (SQ4-SQ6), fault to depression transition stage (SQ7-SQ8), and depression stage (SQ9-SQ10). Through comprehensive analysis of seismic sequence configuration, sequence stacking pattern, and depositional filling characteristics, we established the depositional model of the Aryskum Depression in the South Turgay Basin. It is indicated that there are differences in depositional compositions of sequences formed in different stages. Four stages can be clearly identified: filling stage of fan delta facies-lacustrine facies (Stage I) corresponding to the rapid filling in the early rift stage, filling stage of fan delta facies-lacustrine facies-normal delta facies (Stage II) corresponding to trichotomous characteristics of internal systems tracts in the late rift stage, filling stage of braided river delta facies-normal delta facies-lacustrine facies (Stage III) corresponding to the development of high-stand systems tracts in the fault to depression transition stage, and filling stage of fluvial facies-normal delta facies-lacustrine facies (Stage IV) corresponding to binary characteristics of internal systems tracts in the depression stage. Finally, optimization of favorable exploration strata and prospects in the Aryskum Depression are proposed.

“…During this stage, hydrocarbon source rocks of Quantou Formation (K 1 q), Qingshankou Formation (K 2 qn) and Nengjiang Formation (K 2 n) were deposited in a series of well-developed lakes. The final structural inversion and contraction phase of the Songliao Basin occurred from the Nengjiang Formation (K 2 n) of Late Cretaceous to Cenozoic (Chen, 2012;Wang et al, 2015).…”

“…A great deal of researches have been conducted on the stratigraphic subdivision and sub-correlation as well as depositional models of the Cretaceous across the entire Songliao Basin based on palynological data (Mi et al 2010;Liu et al 2011;Wang et al 2016;Li et al 2018a;Sun et al 2019), tectonic evolution (Feng et al 2013b;Wang et al 2011;Wang et al 2016), depositional environments (Liu et al 2011;Feng et al 2013b), sequence stratigraphic framework (Hu et al 2001;Guo et al 2004;Wan et al 2013;Wang et al 2015),and oil and gas enrichment (Mi et al 2010;Sun et al2019). However, the coal accumulation in relation to the sequence stratigraphy in Songliao Basin continental rift basins are still not well understood, with previous studies being limited to a range of several faulted sags or sub-basins, or only from the perspective of lithological association analysis (Shao et al 2017).…”

The Early Cretaceous is an important coal accumulation period in China. Abundant coal resources were formed in the southeastern margin of Songliao Basin. Sequence stratigraphy and coal accumulation of the Early Cretaceous in the southeastern margin of Songliao Basin have been studied on the basis of extensive outcrop and borehole data. Based on regional unconformity, basal erosional surfaces of incised valley fills, and abrupt depositional facies-reversal surface, six sequence boundaries have been identified, which subdivide the Early Cretaceous coal-bearing series into 5 third-order sequences. Sequence I corresponds to Huoshiling Formation, sequences II and III correspond to member I and member II of Shahezi Formation. Sequences IV and V correspond to member I and member II of Yingcheng Formation. Sequence I developed at the initial subsiding stage, sequence II and III developed during the stable subsiding stage, while sequence IV and V developed during the basin shrinkage stage. The major coal seams were developed in the sequence II and III, which ensured the relative balance between the increase rate of the accommodation space and the rate of peat accumulation for a longer period, thus forming a thick coal seam.
