Indicate an intense degree and a long period of of the lithospheric thinning beneath the fault zone, its occurrence and activities provides an routeway and an important role to magma activities.
During extensional activities of Late Cretaceo us to Eogene, intense upwelling of asthenosphere happened under the fault zone, leading to lithospheric necking in pure shear mode1.
