... but have focused on certain particular sags. For example, Zhang (2000) analyzed the distribution of source rocks on the basis of their tectonic framework, Huang and Li (2002 ) and Huang (2003) evaluated the source rock character of the Dongying Formation of the Bozhong Depression and carried out...

... et al. (2003) , where SD is standard deviation. The offshore Bohai Bay Basin is one of the most petroliferous basins in China. It is surrounded by the Jiaoliao fault-uplift zone to the east, the Liaohe depression to the north, the Jiyang depression to the south, and the Huanghua depression...

... facies exhibited a thick layer and large scale with gypsum and mudstone deposition. The mud-rich facies is characterized by continuous and relatively high-amplitude seismic reflections, and it is mainly developed in the Laizhouwan and Qingdong depression. During the third member of the Shahejie...

... in Africa ( Brun and Fort, 2004 ), the Kuqa Foreland Basin in China ( Li et al., 2012 ; Callot et al., 2013 ), and the Laizhouwan depression in China ( Yu et al., 2009 ) are standard examples of compressional salt structures. Many conceptual models and experimental studies have also been done...

Among them, the Weifang–Jiashan segment is the most active part of the Tanlu fault zone [ 4...

The Bozhong Depression is a subbasin in the Bohai Bay Basin, which is a crucial area for researching the tectonic evolution of the Bohai Bay Basin throughout the Mesozoic–Cenozoic and the regional tectonic evolution of the eastern continental margin...

... plate, Qaidam, Kazakhstan, and Tethys Qiangtang plate. The tectonic movement was frequent, and the strata have been buried for a long time, so it formed a large-scale composite petroleum basin ( Li, 2010 ). The Tarim Basin has eight geologic tectonic units: Kuche Depression, Keping Uplift, Tabei Uplift...

..., in many cases, complex meander-belt deposits with widths smaller than 2 km (∼1 mile) may be mistaken for a single channel story. For example, the fifth sandstone unit from the top of the upper Guantao Formation (N g 5 2+3 ) in Jiyang depression of Bohai Bay Basin ( Figure 1A ) were interpreted as meander...
