Editing Rift (section)

===Mature rift stage===
As the rift evolves, some of the individual fault segments grow, eventually becoming linked together to form the larger bounding faults. Subsequent extension becomes concentrated on these faults. The longer faults and wider fault spacing leads to more continuous areas of fault-related [[subsidence]] along the rift axis. Significant uplift of the rift shoulders develops at this stage, strongly influencing drainage and sedimentation in the rift basins.<ref name="Withjack"/>

During the climax of lithospheric rifting, as the crust is thinned, the Earth's surface subsides and the [[Mohorovičić discontinuity|Moho]] becomes correspondingly raised. At the same time, the mantle lithosphere becomes thinned, causing a rise of the top of the asthenosphere. This brings high heat flow from the upwelling asthenosphere into the thinning lithosphere, heating the orogenic lithosphere for dehydration melting, typically causing extreme metamorphism at high thermal gradients of greater than 30&nbsp;°C. The metamorphic products are high to ultrahigh temperature granulites and their associated migmatite and granites in collisional orogens, with possible emplacement of metamorphic core complexes in continental rift zones but oceanic core complexes in spreading ridges. This leads to a kind of orogeneses in extensional settings, which is referred as to rifting orogeny.<ref>{{cite journal | last1 = Zheng | first1 = Y.-F. | last2 = Chen | first2 = R.-X. | year = 2017 | title = Regional metamorphism at extreme conditions: Implications for orogeny at convergent plate margins | journal = Journal of Asian Earth Sciences | volume = 145 | pages = 46–73 | doi = 10.1016/j.jseaes.2017.03.009 | bibcode = 2017JAESc.145...46Z | doi-access = free }}</ref>
