Abstract: This paper presented the concept of decoupled decollement structures and continental expanding mode under the expanding system, with examples from Tertiary fault-depression basin of Bohai Bay and Jurassic fault-depression basin in Yanji. It is focused on the control function of expanding function on the basin formation and evolution, development of sedimentary systems,various static key factors and dynamic procedure of petroleum systems. It is suggested that oil and gas are inherently correlated with decoupled structures directly or indirectly and are associated in generation and formation.

Key words: decoupled structure, slump structure, basin evolution, peboleum system, Bohai Bay basin, Yanji basin
