The Jiamusi-Yitong falut was the western branch of northern extension of Tan-Lu fault��which con- trolled the distributions of many basins within Jia-Yi graben�� The authous found a ductile-brittle shear zone with trend of NNE in Shuiquliu of Shulan area�� Combining the microstructure study��the authors consider that the shear zone was consisted of protomylonite-mylonite and displayed sinistral strike-slip shear characteristics�� With the meas- urement of finite-strain determination (Fry measurement)��the strain type of the study area was considered to be ex- tension strain�� EBSD (electron back scatter diffraction) measurement also indicated the study area had undergone asinistral strike-slip shear zone and quartz fabrics were mainly low-middle temperature prism-glide fabrics with slip system of {0001} ��110 �� �� To sum up��Shuiquliu shear zone had experienced a sinistral strike-slip shearing in middle-late Early Cretaceous��which was related to moving direction changing from NWW to NNW of the western Pacific Izanagi plate obliquely subducting under the Eurasia plate��
