摘要
From Late Cretaceous to Cenozoic, the Jinhu sag (south-west part of the Subei Basin) developed a complex fault system. The Fault system experienced four stages of evolution:initial extension, inheritance extension, intense extension, and superimposed strike-slip stages. And consequently, the structural pattern of the Jinhu sag was established. The Yangcun and Shigang faults are persistence active faults controlled by the pre-existing basement faults. The Tongcheng fault, a transfer fault which accommodated the strike-slip stress between the Shigang and Yancun faults, was formed in the late stage. The activity of fault system was mainly controlled by the pre-existing faults and region stress filed.
