Kinematics and shear heat pattern of ductile simple shear zones with ‘slip boundary condition’

摘要: Extrusion by Poiseuille flow and simple shear of hot lower crust has been deciphered from large orogens, partial-slip boundary condition encountered in analogue models. Shear heat velocity profiles are deduced a simplified form Navier–Stokes equation for together with extrusive slip Newtonian viscous rheology. A higher at the upper zone promotes boundary. The other parameters that affect viscosity thickness resultant pressure gradient drives extrusion. In case, depending on (resultant gradient, density viscosity) zone, can curve indicate opposite senses. corresponding temperature maximum inside zones near either boundaries or equidistant them.
