Data from 136 observation points of faults and over 200 observation points of joints are obtained. These data belong to several imbricate faults, distributed in a area of 50 square kilometers. Data of joints are processed by a microcomputer. Tectonic stress fields in four generations are distinguished. On the basis of striation study of superimposed fractures and study of associated joints and small folds, using stereographic projection, the superimposed activities for each generation are identified. The kinematic and dynamic features of the superimposed fracture are recognized. The results obtained are in good agreement with optimum shear angle principles.
