  • The investigation of normal fault formed under tectonic setting of upwelling force and its critical stress state is of significance in the structural interpretation and the hydrocarbon migration. Based on the theory of parabolic Mohr failure envelope, and certain assumptions, mathematical derivation and theory modeling being carried out, quantitative functions of geometric shape of normal fault and its critical stress state were given. It is found that the fault dip becomes smaller from shallow to deep, being a listric fault. The rate of dip change is only related to the properties of strata. And the rate of dip change is faster in isotopic sandstone than in mudstone. It is also proved that the depth of the fault is linear against the amplitude of upwelling force. A typical ramp-flat normal fault can be drawn from the fracture modeling of interbedded sandstone-mudstone rock body. Not only are these conclusions consistent with the natural phenomena and general cognition, but also they can explain the geometric shape of faults quantitatively and find the critical stress state.
