| Summary: | Three-dimensional folding behavior of an elasto-viscous layer induced by transpression, and biaxial compression on the boundary is studied. The factors studied include the strain rate, elastic competency contrast, and viscous competency contrast. It was found that the influence of elastic competency contrast fades as the strain rate slows until finally folding behavior is completely controlled by viscous behavior. If biaxial compression is applied, induced folding along each principal stress direction is dependent. The resulting wavelength in any particular direction will not be affected by initial shortening applied in another direction. The final fold form is the supposition of fold forms in two individual directions. |
