Cretaceous Stress Fields Evolution and Its Geodynamic Implications in Jiaolai Basin,Northern China

The Tan-Lu fault zone(TLFZ)along the East China continental margin experienced sinistral movement at the beginning of Early Cretaceous(ca.145)due to fast oblique subduction of the Izanagi Plate in the Pacific Ocean.It can be easily understood according to the Liddell shear model with the NNE-striking sinistral TLFZ for the NW-striking en-echelon graben system west of it.However,theThe Tan-Lu fault zone(TLFZ)along the East China continental margin experienced sinistral movement at the beginning of Early Cretaceous(ca.145)due to fast oblique subduction of the Izanagi Plate in the Pacific Ocean.It can be easily understood according to the Liddell shear model with the NNE-striking sinistral TLFZ for the NW-striking en-echelon graben system west of it.However,the中国科学院地质与地球物理研究所1Vol.9
