【Abstract】 This paper analyses the foreland basin-mountain coupling from the stratigraphy in the foreland basin. The research areas include the Sichuan Mesozoic foreland basin and Erdos Mesozoic foreland basin in the central part of China. The research shows that the foreland basin is relatively well coupled with the orogenic belt. The filling sediment features of the foreland basin mirror the formation and evolution of the orogenic belts and the subsidence of the foreland basin. The migration of the upward-coarsening sedimentary succession and the stratigraphic unconformity toward the direction of the foreland basin reflects the evolutionary process of the consecutive uplift of the orogenic belt toward the foreland. The lithological feature of the sediments in the foreland basin reflects the double-source supply and the orogenic-belt erosion. The structure of the system tracts in the sequence stratigraphy and the stratigraphic accumulation pattern are mainly controlled by the change in the subsidence rate of the foreland basin.更多还原
