摘要
Extensional transfer structure is one of important structural styles in the Jiyang Depression. Based on the attitudes and contact relationships of the dominate faults, twelve kinds of secondary transfer structures have been identified, occurring as relay ramps, cross relief and graben. The secondary transfer structures mainly accommodated the extension of local blocks and resulted in the throw change of dominate faults, where the drainage system flew into the lake and formed alluvial fan and near shore subaqueous fan, which is favourable for hydrocarbon accumulation.
