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, a terrane (/ t ə ˈ r eɪ n, ˈ t ɛr eɪ n /; [1] [2] in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or "sutured" to crust lying on another plate. The crustal block or fragment preserves its distinctive geologic history, which is different from the ...
The continental crust on the downgoing plate is deeply subducted as part of the downgoing plate during collision, defined as buoyant crust entering a subduction zone. An unknown proportion of subducted continental crust returns to the surface as ultra-high pressure (UHP) metamorphic terranes, which contain metamorphic coesite and/or diamond plus or minus unusual silicon-rich garnets and/or ...

Parts of the Trans-European Suture Zone (STZ, TEF and TTZ) are shown as bands of black colour between the North Sea and the Black Sea. 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 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.
The Zagros FTB extends for about 1,800 km (1,100 mi) from the Bitlis suture zone in the northwest to the boundary with the Makran Trench, east of the Strait of Hormuz, in the southeast. The belt varies in width with two main salients (where the thrust belt bulges out towards the foreland) in the Lorestan and Fars domains and two main embayments ...
