THE ROCK RHEOLOGY IN THE FAULT ZONE OF THE SHALLOW LEVEL

A rheological study of the fault zone of the shallow level may concern not only the tectonophysical charactreristics of the deformation but also the genetic mechanism of the kinematics. In this paper authors try to explaning the rheology of solid state controlled by the simple shearing in the shallow structural lecel taking a dip-slip fault at Suzhou Tongshan as an example. Seen from standpoint of the solid rheology the shallow level belongs to the scale of a cataclastic rheology, and can occur the dynamic differentiation, metamorphic differentiation and the local penetrative structure as well. It should be emphasized that the stress orientation of the flow shearing in the reverse fault zone of Suzhou Tongshan parallels to the move direction of the dipslip in this area, and the rock rheology might affect the dislocation forming of the different types.
