Vertical averages of rheology of the continental lithosphere Relation to thin sheet parametersThe calculations of the vertically-integrated strengths of the lithosphere and the Agrand number are described. The crustal and mantle contributions to the vertically-integrated strength, which is approximated from the brittle layer, and the depth and stress difference at the brittle-ductile transtion, is examined. The effective power laws for vertically-integrated rheology, which are dependent on the thermal stability of the lithosphere and the depth to the brittle-ductile transition in the crust, are studied. The relationship between the Agrand number and vertically-integrated strengths of the lithosphere and the thermal regime of the uppermost mantle and the stress state in the upper crust is analyzed.
