江绍断裂带的活动特征初探

s the bourndary of Yangzi Plate and China Block, Jiangshan-Shaoxing Fault Zone is obviously a dividing zone on geology and geophysical in southeastern China. Meanwhile, the Fault Zone is a obvious tectonic belt controling basins along. This article systematically analysised the active features before Tertiary of the Fault Zone, especially paid attention to its active natures after Indosinian, later Mesozoic. During different evolution periods, the Fault Zone had different tectonic natures, but it mainly shown as the collision-shear zone between Yangzi Plate and China Block. It storied first collision-press & making mountain of Jinning Period, stripe-slip of Calenonian Period, relative stableness of Hercynian-Indosinian Period, second collison-press & making mountain of early Yanshanian and stretching of later Yanshanian. After the birth by nearly SN collison of Yangze Plate and China Block in Jinning Period, Jiangshan-Shaoxing Fault Zone lied in press-shear settings for long time, along which were mainly flexture basins and pull-apart basins. With the change of tectonic environment in early to middle Jurassic, the Fault Zone came into stretching stage, along which developed a series of rift basins. During its evolution, the Fault Zone evidently influenced geological progress along. It controlled basins’developing types and sizes in different stage, and influenced the distribution of sediments and mines.
