The rheology of the lithosphere determines its deformation under given initial and
boundary conditions. The rheology of the lithosphere is a function of its composition
and structure, pressure, temperature, and state of stress. The concept of strength
envelope (rheological profile), firstly developed by Goetze and Evans (1979), is well
known (cf. Ranalli, 1995). On the basis of a generalization of experimental results, it
is assumed that the deformation regime for any given rock can be subdivided into two
domains: brit-tel or frictional, governed by the Coulomb-Navier shear failure
criterion, and ductile, governed by the power-law creep equation. The brittle/ductile
transition is defined by the equality of frictional strength and ductile strength (for a
given strain rate). In this article we review the lithosphere and its behavior by various
rheological law based on rock composition, temperature(cold), pressure, with simple
numerical model (block in NW-SE Iran) .
