TL;DR: In this article, the Huangxian Basin was chosen as a typical example to study the mechanism of sedimentation of coal and oil shale, and a sequence stratigraphic framework with two sequences (each including three systems tracts) was established to analyze the depositional evolution.

TL;DR: The coal-bearing strata in China have complicated geneses and di... as discussed by the authors, which are extensively developed in marine-influenced, continental, and transitional environments, and the coal resources are abundant in China.

TL;DR: In this paper, the sedimentary models of coal and shale associations are very important to expander the coal-and-shale associations in the Huangxian Basin, which lies in Eastern China.

TL;DR: Yacheng Formation has been divided into one cycle sequence of ultra long-period, three cylce sequences of long period and 12 cycle sequences of intermediate period based on data from comprehensive drilling cores, logging, the seismic survey and former studies.

TL;DR: In this paper, the authors investigated the geotectonic basis of coal and oil shale coexistence and concluded that the basins' tectonic activity controlled the overall characteristics of basin filling, and thus represented the external conditions for the coexistence of coal.
