| Abstract: | Zhenhai fracture belt formed in the Late Yanshanian tectonic movement, It is the major tectonic belt in Ningbo area. On the basis of field observations, stru-ctural deformation analysis in Zhenhai fracture belt,in terms of striation measure-ment on fault planes, analysis of conjugate joints and microstructures near the fracture belt,the stress direction of the Late Yanshanian stress fields is determin-ed. In the meantime, According to the rock fracturing theory, and the calcite twin lamellae and dislocation density in the deformed quartz, the differential str-ess is estimated. |
