The second model involves derivation of the melts from a depleted lithosphericmantle source which was contaminated by subduction components. The evidence, including that of xenoliths carried in the magmas, supports the idea of melting of old metasomatized lithosphericmantle, usually associated with rifting tectonics. Tracking changes in sub-continental lithosphericmantle through time. A certain degree of coherence should exist within the crust and between the crust and lithosphericmantle. Such melts thus preserve the best evidence for the composition of sub-continental lithospheric mantle, particularly for the origin of mantle enrichment. Consequently, the lithosphericmantle was highly affected by an old continental component. During the earlier extension stage immediately following the orogeny, some older enriched lithosphericmantle components might be incorporated into the depleted asthenospheric mantle. It is believed that the pre-existing metasomatized lithosphericmantle would be easily melted during the post-orogenic extension. Thus, the lithosphericmantle in the region was not strongly affected by old continental crustal components. We therefore favour the model whereby the eclogitic lower crust, together with the underlying lithosphericmantle, was delaminated, accompanied by asthenosphere upwelling. Its subduction-related geochemical features are inherited from an enriched lithosphericmantle which retains earlier subduction signatures. Does the lithosphericmantle play a major or a subsidiary role in orogenic processes? This belief had a major advantage: it was possible to deal separately with the deformation of the lithosphericmantle, of the lower crust and of the upper and middle crust. The parental magma was derived from melting of a long-term enriched sub-continental lithospheric mantle source as is indicated by the highly enriched isotopic signatures of the lamprophyres. Far field stresses thin the crust and lithosphericmantle, and hot asthenospheric mantle passively enters the thinned area.

This is because cratons are very thick, and their lithosphericmantle extends to great enough depth that diamonds are stable.

Separation of lowermost crust and lithosphericmantle is controlled by the effective viscosity of the upper continental crust.

This thickening occurs by conductive cooling, which converts hot asthenosphere into lithospheric mantle and causes the oceanic lithosphere to become increasingly thick and dense with age.
