Each sequence is composed of incised valley sandstone of lowsystemtract, limestone, marl, coal and mudstone of transgressive system tract and clastics and coal of high system tract.
The carbonate source rock is controlled by system tracts and facies. The carbonate source rock is mainly developed in high systemtract in low ramp or is survived with gypsum-salt rock together.
