Abstract: Sedimentary geology of orogenic belts famed another benchmark in sedimentology since the emergence of sequence stratigraphy,is a synthetic branch of science including stratigraphy,sedimentology,tectonics,geophysics and geochemistry.In this paper,em-physis is laid on the theoretical train of thoughts and methodology for the study of sedi-mentary geology of orogenic belts,adopting the entire analysis,synthetic analysis,back-ground analysis and evolution analysis in basin analysis under the guidance of the mobil-ism,as well as on the selection of the contents and steps on the basis of the architecture of orogenic belts and the distribution patterns of basins and oceans.Most contents and multi-disciplinary approaches of regional stratigraphy,sedimentology,tectonics,stratigraphic successions and sedimentary evolution,palaeogeography palaeo-oceanography as well as dynamic sedimentology and evolutionary patterns are involved in the study of sedimentary geology of orogenic belts.
