The Tan-Lu active fault zone is an important tectonic boundary in east China. Minor structures associated with the fault show that the nature of displacement on the middle segment of the fault zone has changed in consecutive episodes since the Cretaceous: normal faulting during the Cretaceous, sinistral strike-slip and reverse faulting at the end of the Cretaceous or in the early Tertiary, and dextral strike-slip and reverse faulting from the late Tertiary to the present. The regional orientation of the maximum principal compressive stress, based upon the statistical study of minor shear fracture orientation, is 6°, S52°W in the late Tertiary to Quaternary. This stress field may be related to the collision between India and Tibet and the microspreading of the Japan Sea. © 1983.
