21. The Black Hills of South Dakota is one of the few remaining exposed portions of the Trans-Hudson orogenic belt . 22. The Steep Belt effectively marks the southeastern edge of the intensely folded region of the Caledonian Orogenic Belt in central Wales. 23. It is also the southern continuation of the Thelon Magmatic Zone, an orogenic belt between the Slave and Churchill cratons. 24. It is important to separate local from large-scale tectonic history of the orogenic belt in order to understand the orogeny. 25. In geology the "'Ukrainian Shield "'( or Ukrainian Crystalline Massif ) is the southwest orogenic belts . 26. The Central Orogenic Belt is mainly rocky mountains up to 2, 360 metres ( 7, 740 ft ) in elevation. 27. The "'Merisi Mining District "'is situated in Adjara region in close vicinity to the orogenic belt . 28. Prior to 1550 Ma the craton comprised a number of active Proterozoic orogenic belts extending back in time to at least 2450 Ma. 29. At the same time, the internal zones of the orogenic belt were affected by large extensional structure of the back-arc Pannonian Basin. 30. Here, the orogenic belt attains a trapezoidal shape dominated by oblique splay faults, steeply-dipping recumbent nappes and fault-bend folds.
