Abstract
This paper reports the kinematics and deformation history of the fault rocks along the Shajigami Shear Zone in the South Kitakami Belt, eastern margin of Abukuma Mountains, Northeast Japan. Sinistral ductile shear converted andesites, schistose granodiorite and granodiorite porphyry into mylonites under the condition of ductile-brittle transition regime. The Soma Paleozoic Formations also underwent sinistral shearing along the Shajigami Shear Zone. Cataclasites and calc-mylonite are distributed along the Shajigami Fault in the Shajigami Sear Zone. Asymmetric microstructures of the foliated cataclasite and fabrics of calcite grains in the calc-mylonite suggest the occurrence of the dextral shear with shortening which was overprinted after the sinistral ductile shear movement. -after English summary
