Tectonics of the Polar Urals – Novaya Zemlya fold belts

Abstract
The tectonic relationships of the Pay-Khoy-Novaya Zemlya and Ural fold belts are discussed. Traditionally, in geological literature, the former is considered to be Early Cimmerian and the latter, Caledonian-Hercynian. Based on results of geological mapping, it is shown that tectonic movements in the Polar Urals affected the Pay-Khoy structures, thus, the ideas about the later Early Cimmerian age of the Pay-Khoy structures’ formation are erroneous. The authors substantiate the belonging of both areas to the unified Ural-Novaya Zemlya fold system, which completed its formation at the Triassic-Jurassic boundary, the migration of the main phase of folding from east to west from the Permian to the Triassic, and the existence of hypothetical Paleozoic ophiolite and island-arc associations north of the Pay-Khoy.
