Abstract: Using the estimating method of earth crust deformation velocity from the displacement of the opposite walls of Tan-Lu fault zone, the maxim um sinistral strike-slip of the fault zone is suggested as 390km. According to the displacement of south marginal fault of Sino-Korean block, the maximum sinistral strike-slip of Tan Lu fault zone is estimated to be 430km. By the paleomagnetic method, the strike slip is about 300-400km. The forming age of maximum sinistral strike-slip occurred in Middle-Late Triassic. In Jurassic, the Tan-Lu fault was a reverse one. The strike slip in Cretaceous was more than 100km, and that in Eogene was unclear. In the Neogene Early Pleistocene, about 50km of sinistral displacement occurred along the Tan-Lu fault zone. From 0.73Ma on (Neotectonic stage), the dextral strike slip is less than 100 m.
