Abstract: According to the accommodation structure theory, in combination with the analysis on geological map and paleo-fall, five accommodation zones and seven structure forms have be recognized in Jizhong Depression.The synthetic approaching-type accommodation zone can occur as nose structure, horst and transform fault, e.g., it occurs as nose structure exist in fault segment joints, but as coexistence of transform fault and transverse salient in the joints of faults controlling depression.The synthetic overlap-type accommodation zone transfers strain in the form of trend slope.The synthetic collateral-type accommodation zone reforms the Hexiwu buried hill belt in the form of warping.The convergent collateral-type accommodation zone develops in Yanling area in the form of low uplift.The convergent approaching-type accommodation zone, typically observed in the Maozhou hub zone, forms double-layer deformation system, which comprises a bottom of fault bifurcation oblique slip and an upper of wide cup zone.In the geological evolution, a relation of ebb and flow can be obserbed among the activity intensities of the faults which play the part of accommodation.With the effect and reformation of accommodation zone, a migration path for oil and gas, with ancient structural ridge as dominant migration pathway, can be formed on the slop of buried hill.
