Structural parageneses of flysch complexes in the central part of the Uralian Foreland basin

Abstract

In this work we reported the structural characteristics of the late Paleozoic flysch formation in the central part of the Uralian foreland basin. Three types of structural associations specific for thrust zones are established there. These include: 1) asymmetrical to recumbent west-vergent folds; 2) re-structured tectonic melange; 3) local thrusts, zone of schystosity, flat tectonic mirrors. Generally structural elements strike approximately parallel to the regional Karantrav thrust; orientation of striking ranges from the northwest to the northeast, accordingly to tectonic heterogeneity of the allochtone.
