==Main types of tectonic regime== ===Extensional tectonics=== {{Main article|Extensional tectonics}} Extensional tectonics is associated with the stretching and thinning of the crust or the [[lithosphere]]. This type of tectonics is found at divergent plate boundaries, in continental [[rift]]s, during and after a period of [[continental collision]] caused by the lateral spreading of the thickened crust formed, at releasing bends in [[Fault (geology)#Strike-slip faults|strike-slip faults]], in [[back-arc basin]]s, and on the continental end of [[passive margin]] sequences where a [[Décollement|detachment layer]] is present.<ref>{{citation|url=http://bmeyer2.free.fr/pdf/2002-TerraNova.pdf|last1=Armijo|first1=R.|last2=Meyer|first2=B.|last3=Navarro|first3=S.|last4=King|first4=G.|last5=Barka|first5=A.|author-link5=Aykut Barka|year=2002|title=Asymmetric slip partitioning in the Sea of Marmara pull-apart: a clue to propagation processes of the North Anatolian Fault?|journal=Terra Nova|publisher=[[Wiley-Blackwell]]|volume=14|issue=2|pages=80–86|doi=10.1046/j.1365-3121.2002.00397.x|bibcode=2002TeNov..14...80A|citeseerx=10.1.1.546.4111|s2cid=49553634 }}</ref><ref name="Sdrolias_&_Muller_2006">{{Cite journal|last1=Sdrolias|first1=M|last2=Muller|first2=R.D.|date=2006|title=Controls on back-arc basin formations|journal=Geochemistry, Geophysics, Geosystems|volume=7|issue=4|pages=Q04016|bibcode=2006GGG.....7.4016S|doi=10.1029/2005GC001090|doi-access=free|s2cid=129068818}}</ref><ref name="Brun_&_Fort_2011">{{Cite journal |last1=Brun |first1=J,-P. |last2=Fort |first2=X. |title=Salt tectonics at passive margins: Geology versus models |journal=Marine and Petroleum Geology |date=2011 |volume=28 |issue=6 |pages=1123–1145 |doi=10.1016/j.marpetgeo.2011.03.004|bibcode=2011MarPG..28.1123B }}</ref> ===Thrust (contractional) tectonics=== {{Main article|Thrust tectonics}} Thrust tectonics is associated with the shortening and thickening of the crust, or the lithosphere. This type of tectonics is found at zones of [[continental collision]], at restraining bends in strike-slip faults, and at the oceanward part of passive margin sequences where a detachment layer is present.<ref name="Butler_&_Bond_2020">{{Cite book |last=Butler |first=R. |title=Principles of Geologic Analysis |last2=Bond |first2=C. |publisher=Elsevier |year=2020 |isbn=9780444641359 |editor-last=Scarselli |editor-first=N. |edition=2 |series=Regional Geology and Tectonics |volume=1 |pages=149–167 |chapter=Chapter 9 – Thrust systems and contractional tectonics |doi=10.1016/B978-0-444-64134-2.00008-0 |editor-last2=Adam |editor-first2=J. |editor-last3=Chiarella |editor-first3=D.}}</ref> ===Strike-slip tectonics=== [[File:Aerial-SanAndreas-CarrizoPlain.jpg|thumb|[[San Andreas Fault|San Andreas transform fault]] on the [[Carrizo Plain]]]] {{Main article|Strike-slip tectonics}} Strike-slip tectonics is associated with the relative lateral movement of parts of the crust or the lithosphere. This type of tectonics is found along oceanic and continental [[transform fault]]s which connect offset segments of [[mid-ocean ridge]]s. Strike-slip tectonics also occurs at lateral offsets in extensional and [[thrust fault]] systems. In areas involved with [[Continental collision|plate collisions]] strike-slip deformation occurs in the over-riding plate in zones of oblique collision and accommodates deformation in the [[Foreland basin|foreland]] to a collisional belt.<ref name="Burg_2017">{{Cite web |last=Burg |first=J.-P. |date=2017 |title=Strike-slip and Oblique-slip tectonics |url=https://www.files.ethz.ch/structuralgeology/jpb/files/english/5wrench.pdf |access-date=26 September 2022}}</ref>
