| Abstract: | Based on the systematic finite strain measurement the featured of the shear deforms-tion along Dongshan segment of the Changle-Nanao fault zone are analyxzed Differential stress is estimated by using microstructures of the deformed quartxz from the Discrete calcultion of deformation energy density distribution across the shear the numerical soiution to the shear heating is obtained throunh finite differential equation and finally the relative temporal and spatial relatioship among shear deformation shear heating and dynamothermal petromineralization in the study area and the regional tection implication of the Changle Nanao fauit zone are summarized in this paper. |
