Editing Rift (section)

===Rift initiation===
The formation of rift basins and strain localization reflects rift maturity. At the onset of rifting, the upper part of the lithosphere starts to extend on a series of initially unconnected [[normal fault]]s, leading to the development of isolated basins.<ref name="Withjack">{{cite book|last=Withjack|first=M.O. |author2=Schlische R.W. |author3=Olsen P.E.|title=Sedimentation in Continental Rifts|editor=Renaut R.W. & Ashley G.M.|publisher=Society for Sedimentary Geology|year=2002|series=Special Publications|volume=73|chapter=Rift-basin structure and its influence on sedimentary systems|chapter-url=http://www.rci.rutgers.edu/~schlisch/A33_2002_SEPM_rifts.pdf|access-date=28 October 2012}}</ref> In subaerial rifts, for example, drainage at the onset of rifting is generally internal, with no element of through drainage.
