Summary:While the frictional strength of the upper crust is high, the frictional resistance to motion along transform plate boundaries is very low. The horizontal principal stresses must therefore be orientated [vertical bar][vertical bar] and perpendicular the transform-fault zone to minimize shear stresses acting [vertical bar][vertical bar] the transform. Near-fault normal compression and fault-normal crustal shortening is expected along plate margins accommodating relative convergence (transgressive margins). Along transtensional margins extension is expected to occur perpendicular the transform. [R.K.H.]
