Deforming responses and its identification characteristics of flexing

Key words:  flexing  flexing zone  winding flexural zone  deformation  tectonic sequence  transport system

Abstract:

The deforming responses and seismic responses of the flexing were analyzed, and the tectonic units, dynamic context and the sedimentary sequences were studied. The results show that the flexural-slipping induced by flexing occuits on li-thological interface and flexural-slipping interface formed by flexing. These two different genetic horizons exhibit unique seismic response. High-competent strata and ductile strata can exhibit different strain characteristics under the same flexural stress, the former is dominated with the brittle strain such as the fault and fracture，the latter correspond to necking，ductile flow, plastic creep, crumpling etc. All these characteristics strain constitute the cubic, large-scale, interconnected meshwork including intra-bed faults or fractures f opened fissures, slipping surface, and detached fissures. This meshwork make the fluid flow, physico-chemical action, water-rock action more practical. The meshwork is quite different from the conventionally transport systems which consist of faults, permeable sandstone strata and unconformities.
