Planar strips,vertical stages,continuous backpedal and strong succession are the characteristics of the glutinite body distribution in a rift extensional basin.
10.basement and unmetamorphosed terrigenous shallow carbonate rock in the Austria Alps -South Alps obduc-tion nappe and radiolarian silicalite in fault basins.
The sequence classification and dynamic analysis of this basin provide an important evidence to the stratigraphic correlation, tectonic analysis and minerogenesis.
Ichnofabric analysis displays a rising significance on accurate environmental interpretation of sedimentary units in oil-bearing basin and precise recognition of depositional disconuities.
The area had undergone such evolution stages as passive borderland basining, squeerze-retrograde nose-like swelling, cratonic inner sagging. intracratonic basining and para-foreland basin.
These basins were generally filled with upward fining and deepening sedimentary sequence that comprises nonmarine to marine, shallow marine to deep marine depositional systems.
