“…However, no study based on tectono-sequence stratigraphy has been carried out to determine the relationship between accommodation zones and stratal architecture variability. Following our previous investigation on the sedimentary architecture of the sublacustrine fans of the Fushan Depression (Liu et al, 2014), the present study analyses the sequence architecture and depositional systems in different structural provinces along the southern slope of the Fushan Depression, attempting to highlight the spatial controlling effect of the accommodation zone on stratal architectural variability.…”

“…It is a "dustpan" shaped depression bounded by the Qiongzhou Strait to the north, the Hainan Uplift to the south, the Lingao Uplift to the west and the Yunlong Uplift to the east ( Fig.2) (Li et al, 2007;Liu et al, 2012). Accumulating sediment is supplied through braided river deltas mainly from the southern margin (Li et al, 2008;Liu et al, 2014). In a similar manner to many other continental basins (Nelson et al, 1992;Feng et al, 2013), it is characterised by multiphase structural superposition of deposits and multistage volcanic activity, and is therefore a challenging environment to explore for hydrocarbons (Li et al, 2007;Liu et al, 2014).…”

One remarkable structural character of this basin is the occurrence of two vertically superposed sets of fault systems, including a deep south-dipping fault system and a shallow north-dipping fault system (Luo and Pang, 2008).…”

“…Based on major parallel unconformities, the Palaeogene unit of the Fushan Depression is divided into three formations: the Changliu Formation (SQEch) of Early Eocene age, the Liushagang Formation (SQEls) of Middle to Late Eocene age, the Weizhou Formation (SQEwz) of Oligocene age (Fig.3) (Li et al, 2010;Liu et al, 2012;Liu et al, 2014).

Three systems tracts can also be recognized in each third-order sequence of the Liushagang Formation: lowstand systems tract (LST), transgressive systems tract (TST) and highstand systems tract (HST) Liu et al, 2014).…”

Temporal and spatial distribution of Cenozoic igneous rocks in the South China Sea and its adjacent regions: implications for tectono‐magmatic evolution

The ocean–continent transition/conjunction zone is a mysterious and significant region in global tectonics and geodynamic evolution. The South China Sea (SCS) is one of the largest marginal basins in the Western Pacific with significant Cenozoic magmatic activities. The relationship between the tectono‐magmatic evolution and the tectonic setting of these Cenozoic igneous rocks is still controversial. In this study, the interpretation of gravity data, magnetic observation and seismic profiles is combined to identify the Cenozoic igneous rocks in the SCS and adjacent regions, and more than 70 magmatic activities have been discerned. We also show how the tectonic movements control the lithology and distribution of these magmatic activities. These Cenozoic magmatic rocks are related to the pre‐spreading, syn‐spreading and post‐spreading of the SCS. We suggest a geodynamic evolution of the SCS according to the temporal and spatial distribution of the igneous rocks. (1) An early period of bimodal volcanism (>32 Ma ago) mainly happened in the Paleogene basins at the northern margin of the SCS. This earlier volcanism happened under a trans‐extensional regime, which resulted from the collision between the Indian and the Eurasian plates since the early Cenozoic. The magmatic rocks may be related to the NNE‐trending right‐stepping dextral strike‐slip faults and the syn‐kinematic pull‐apart basins. These igneous rocks are mostly NNE trending. It is consistent with the Cenozoic dextral trans‐extensional tectonic setting in the East Asian Continental Margin. (2) Syn‐spreading igneous rocks first formed in the Northwest Sub‐basin of the SCS, and then later in the Central and Southwest sub‐basins. The mechanism of the magmatic emplacement results from the NNE‐trending right‐stepping dextral strike‐slip pull‐apart tectonic activity. (3) The spatial alignment of the Quaternary post‐spreading basalts is nearly E–W‐trending, and the different magmatic zones are segmented by NNE‐trending strike‐slip faulting. These volcanics are under an extrusion regime, which resulted from the arc–continent collision between the Luzon–Taiwan Arc and the Eurasian Plate due to the continuously WNW‐directed indentation of the Philippine Sea Plate during the period 9–6 Ma ago. In addition, the nascent NNE trending and dextral Changle–Nanao Fault may have played a significant role in the southward extrusion of the Taiwan Island Arc and the southeast SCS, resulting in an E–W‐trending distribution or strike of the volcanics and normal faults. In Indochina and the Malay Peninsula, widespread Cenozoic extensional post‐spreading granitic plutons are possibly derived from the mantle plume. Magnetic anomaly interpretation and tectonic analysis on these mafic rocks suggest that they were controlled by the Ailaoshan Red River left‐lateral ductile strike‐slip fault zone.

Large sublacustrine fan deposits have been identified within the lacustrine successions of the second member of the Palaeogene Dongying Formation in the Liaozhong Depression. In this study, by using comprehensive and detailed analyses of the borehole lithology, limited cores, wireline logs, and seismic facies, 4 types of sublacustrine fan deposits were identified and characterized. Then, an integrated depositional model was established based on the above investigations. The result indicates that the geophysical characteristics of the different sublacustrine fan deposits differed from each other, in terms of their internal configuration and external geometry of seismic reflections, and stacking patterns of wireline logs, and stratigraphic position in the vertical successions. Subsequently, the model was established according to the comprehensive analysis of the geophysical characteristics and stratigraphic position. The discussion of developing conditions and hydrocarbon discoveries within different types of sublacustrine fan deposits provided robust insights regarding how to locate and evaluate reservoirs in such deposits. Furthermore, the results of this study may potentially assist in achieving a new understanding of how to identify sublacustrine fan deposits in similar lacustrine basins and may also assist in making further decisions regarding the terms of hydrocarbon migration and accumulation.
