Abstract:The southern Shandong Province extends across the Luxi and Ludong fa-ulted blocks. The Yishu Fault Zone, a great NNE-trending fault zone, goes through its centre. The structure of this area is very complex. Under the combined action of the regional principal compressive stress in NE-SW direction and the equilibrium of matter in the depth, the crust has characteristics of intermittent movement of multiphase uplifting and steadying since the neote-ctonic period, resulting in the formation of the layer landforms, such as terraces, planation surfaces and moderate-low hills, which have controlled the distribution of sediments of different origins deposited since the Early Tertiary. In general, the discrepant movement within the two blocks on the two sides of the Yishu Fault Zone has weakened since the neotectonic period. The early formed basins have been eroded while some faulted basins have developed successively on the borders of blocks and some new faulted basins and uplifts have been formed within the Yishu Fault Zone, showing that the blocks have the nature of integral movement. The rising value of the Luxi block is greater than that of the Ludong block and the rate during Late Quaternary is greater than that during Early Quaternary, which indicates the intensity of crustal vertical movement is inhomogeneous in time and space.
Keywords:southern Shandong Province    neotectonic period    vertical movement of the crust
