Web[2] Lithospheric modification during continental rifting is an axiomatic consequence of plate tectonic processes. The processes whereby the continental crust is modified by magmatism during the progressive evolution from continental rifting to seafloor spreading, are however poorly constrained. Web15 mei 2002 · When extension is characterized by lower velocities, the lithosphere reacts differently. The results of one representative test (total extension rate of ∼6 mm/yr) have been selected to illustrate this.

Webshear extension of the lithosphere is modeled as occurring along a straight shear zone. Two parameters define the simple shear model: the dip of the shear zone and its width. Likewise, the pure shear model is defined by two variables: the initial width of a vertical zone of pure shear extension and the rate of change of its width.
