Central and North Asia

Urals Transect, Central Russia
Transect across a major Late Palaeozoic continental collision zone, the Uralian Orogen, within central Russia. Collision zone marks the collision of the East European Craton with the Siberian Craton and intervening terranes of oceanic, island arc and micro-continental origin.

Geophysical Profile 973 Transect, Tibet Plateau
Transect crosses a continent -scale dextral shear zone in the northeast margin of the Tibet Plateau. The transect shows the northward-moving Tibetan Plateau is squeezing the cratons of northern China eastwards ("tectonic escape process") and creating a series of continental-scale sinistral (left-lateral) shear zones (transcurrent fault zones).

Urals Reflection Transect, central Russia
Transect crosses the southern Urals Mountains within central Russia, between Ufa and Kartaly. Transect shows a features of a Palaeozoic orogen that resulted from the Middle to Late Paleozoic collision of the East European Craton with a Sibirian-Kasachian terrane agglomerate. The Transect shows that the Uralides have a significant crustal root in a low-relief region and that there is a doubly-vergent fabric within the collisional belt.

Tibetan Plateau Transect, northern India - Tibet
Transect across the eastern part of Tibet crossing the Lhasa, Qiangtang and Songpan-Ganzi Terranes. The transect shows images of the crust and upper mantle beneath Tibet. Results provide information on the collision between India and Eurasia and that the Indian crust and mantle lithosphere was underthrusting the Lhasa terrane.
