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 north-western part of the zone was created by the collision of Avalonia and Baltica / East European Craton in the Late Ordovician . The south-eastern part of the zone, now largely concealed by deep sedimentary basins, developed through Variscan and Alpine orogenic events.
5-729: Various branches of the TESZ go under different names: The latter two branches (STZ and TEF) span a triangular area of numerous faults, called the Tornquist Fan . In 1893 the Polish geologist Wawrzyniec Teisseyre suggested the existence of a buried tectonic line close to the Carpathian Mountains . As part of his work on a Geological Atlas of Galicia he mapped the line from Galicia in Ukraine to south-eastern Poland. In 1908
10-760: The Baltic Sea to the Dobruja at the Black Sea , is primarily known from geophysical studies. Seismic data and gravity models suggest a strong contrast in crustal thickness, with 28–35 km down to the Moho to the west of the suture and 42–47 km to the east of it. The suture is believed to be buried under thick upper Paleozoic and Mesozoic sediments, and located further west than indicated by historical surface observations.

15-705: The German geologist Alexander Tornquist mapped the continuation of the zone from Poland to Scania in Sweden. Whereas the south-eastern part of the TESZ (Teisseyre-Tornquist Zone) is relatively well-confined, the north-western part divides into numerous sutures and faults, which fan out towards the North Sea and the Iapetus Suture which runs between the Scandinavian and Scottish Caledonides . It includes
20-573: The following linear features (sorted from the north-east): The Moho under the Tornquist Fan has a strong topography with depths varying between 26 and 48 km. It started forming during the Caledonian orogeny as a microcontinent or a series of terranes of Avalonian origin amalgamated with Baltica . Faults are believed to have continued forming until late Paleozoic . The Teisseyre-Tornquist Zone (TTZ), extending from Pomerania at
25-865: Was a Polish geologist. He is known for his work on the southern part of the Trans European Suture Zone and Galician and Romanian geology. Wawrzyniec Teisseyre was born in Kraków , Austrian Empire of French ancestry. He studied at the University of Vienna and the Mining Academy in Leoben (Austria) and worked at the institutes of geology in Vienna and Bucharest. As part of his work on the Geological Atlas of Galicia, he mapped
