Abstract: Tan-Lu fault zone is the great strike-slip fault in eastern of China. It is composed of Yilan-Yitong fault zone and Dunhua-Mishan fault zone in the north of Shenyang city. In this paper we study Yilan-Yitong fault zone by selecting RS data and DEM data. We divide the fault into three segments according to the geometrical and geomorphologic characteristics of each segment. Shenyang-Kaiyuan segment is a single fault that separating Xialiaohe plain and Liaodong Mountains. Kaiyuan-Yilan segment is the asymmetric fault having two boundaries. The graben is formed in the middle of two boundaries separating Songliao basin and Nadanhada Mountain. Yilan-Luobei segment is the dividing line of the Xiaoxing'an rang and Sanjiang basin. The displacement of the rivers and the other faults due to Tan-Lu fault shows the development history of sinistral strike slip early and dextral strike slip later. In addition, we described in detail Yitong graben, and proved the northwest boundary is the main fault by using DEM data in Yitong graben area.

Key words: Tan-Lu fault zone, Yilan-Yitong fault zone, Yitong graben, Remote sensing
