This paper described in detail the structural features of the central Tianshan block along Houxia-Wuwamen section of the Wulumuqi-Korla highway. Basing upon field and microstructural observations, three ductile shearing zones associated with the Central Tianshan Block are identified. The ductile shearing zone occurred along the Northern Margin of the Central Tianshan block has been studied before, and is dextral with a width up to 10km. The Wulasitai ductile shearing zone occurred within the Central Tianshan block, and is a sinistral one, where its mylonite has a width of 200 m. The ductile shearing zone occurred along the southern margin of the Central Tianshan block is presented as a lot of dioritic mylonite and ultra mylonite. Shearing criteria such as S-C fabric indicated that it is a sinistral shearing zone. The boundary faults that were used to define the Central Tianshan block developed along the shearing center of the northern or southern ductile shearing zones respectively. Above shearing zones must have very large strain accumulations, suggesting the amalgamation of the tectonic units of the Tianshan range result from strike sliding in a great degree. It is significant to study the space distribution, kinematics and total strain accumulation of the ductile shearing zones for reconstruction of the tectonics and paleo-geography of the Tianshan range.
