Lithospheric thinning
WebLithospheric thinning also requires isostatic adjustment that is accomplished by (passive) asthenosphere upwelling, and rift subsidence. However, this introduces another critical … Web15 aug. 2000 · (a) Pure shear model: Crust and mantle stretch and thin uniformly at all depths. (b) Distributed shear model: Thinning of the lithospheric mantle is distributed over an area larger than that of upper crustal stretching so that the maximum lithospheric thinning is less than in the pure shear model.
