In structural geology, a suture is a joining along a major fault zone, of separate terranes, tectonic units that have different plate tectonic, metamorphic and paleogeographic histories. The suture is often represented on the surface by an orogen or mountain range.
The red line shows where the Iapetus Suture extends through present-day Ireland and Great Britain. A related suture through Denmark, Poland and Ukraine is the Trans-European Suture Zone. The Iapetus Suture is one of several major geological faults caused by the collision of several ancient land masses forming a suture.
In geology, continental collision is a phenomenon of plate tectonics that occurs at convergent boundaries. Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together. Continental collision is only known to occur on Earth.
The Wilson cycle theory is based upon the idea of an ongoing cycle of ocean closure, continental collision, and a formation of new ocean on the former suture zone.The Wilson Cycle can be described in six phases of tectonic plate motion: the separation of a continent (continental rift), formation of a young ocean at the seafloor, formation of ocean basins during continental drift, initiation of ...
The Trans-European Suture Zone (TESZ), also known as the Tornquist Zone, is the crustal boundary between the Precambrian East European Craton and the Phanerozoic orogens of South-Western Europe. The zone runs from the North Sea to the Black Sea .
The Indus-Yarlung suture zone or the Indus-Yarlung Tsangpo suture is a tectonic suture in southern Tibet and across the north margin of the Himalayas which resulted from the collision between the Indian Plate and the Eurasian Plate starting about 52 Ma. [1] The north side of the suture zone is the Ladakh Batholith of the Karakoram-Lhasa Block.
Suture (geology) – Joining together of separate terranes along a major fault zone Great Falls Tectonic Zone – Major intracontinental shear zone between the Hearne craton and Wyoming craton; Huincul Fault – Fault that extends from the Neuquén Basin eastwards into the Argentine Shelf; Iapetus Suture – Ancient geological fault
The Bangong suture zone is a key location in the central Tibet conjugate fault zone. Approximately 1,200 km long, the suture trends in an east–west orientation. [ 2 ] Located in central Tibet between the Lhasa (southern block) and Qiangtang (northern block) terranes, it is a discontinuous belt of ophiolites and mélange [ 1 ] that is 10–20 ...
