The distributions of slip rate and ductile deformation in a strike- slip shear zone
A simple mechanical model and dimensional analysis are used to derive a scaling law for the partitioning between slip rate on a strike-slip fault and distributed deformation in the far-field. The depth of the fault, the distributions of stress, strain rate and slip rate are solved for a given far-field force or displacement in a 2-D medium with a linear temperature-dependent viscous rheology. A...
متن کاملAn alternative kinematic interpretation of Thetis Boundary Shear Zone, Venus: Evidence for strike-slip ductile duplexes
[1] On Venus a 1000-km-long, 50to 200-km-wide, anastomosing shear zone system (Thetis Boundary Shear Zone (TBSZ)) separates the eastern Ovda and northwestern Thetis Regiones. Previous workers mapped a part of this shear zone and interpreted it as a sinistral strike-slip shear zone containing an extensional jog. In the present study it is reexamined for a detailed structural and kinematic analys...
متن کاملViscoelastic deformation for a clustered earthquake cycle
[1] The clustering of earthquakes in time on the same fault affects the rate and pattern of interseismic deformation. We develop a simple analytic viscoelastic model of the surface velocity field through a clustered earthquake cycle by superposing the velocities of individual earthquake cycles of constant period but varying phase. Velocity profiles prior to and after an earthquake show a wider ...
متن کاملModeling of viscoelastic shear: A nonlinear stick-slip formulation
We present a class of nonlinear dynamic viscoelastic models for materials subjected to shear stress. The model equations are based on a continuum variation of a reptation model in which chemically cross-linked (CC) systems of molecules act as constraint boxes per unit volume for physically constrained (PC) systems of molecules. Results from validating the model with dynamic shear experiments ar...
متن کاملA ductile shear zone terminating a brittle strike-slip fault: The gypsum- dominated Paluzza-Comeglians shear zone as western extension of the Fella- Save fault, Southern Alps
Compressive and extensive horsetails are common structures on the lateral termination of brittle strike-slip faults, which forms within the shallow continental crust. Here we report another possibility, the lateral termination of a brittle strike-slip fault in a formation-parallel low-temperature ductile shear zone within sulphatic, gypsum-dominated evaporites. In the Southern Alps, over a dist...
