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 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 ...

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.
However, a man needed to accept the honor for her benefit, since the Geological Society of London did not permit women to go to its gatherings at the time. [10] [11] 1893: Florence Bascom became the second woman to earn her Ph.D in geology in the United States, and the first woman to receive a Ph.D from Johns Hopkins University.
The Association for Women Geoscientists (AWG) is an international professional organization which promotes the professional development of its members, provides geoscience outreach to girls, and encourages the participation of girls and women in the geosciences. Membership is open to all who support AWG's goals.
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.
