Abstract

Structural-geomorphological analysis of the modern relief allowed us to reveal patterns in the newest structure of Western Taimyr and to show the significance of the shear horizontal displacements of structural forms, as well as the manifestation of previously formed thrusts on the relief in some areas. The neotectonic evolution of the Arctic region has been controlled by opening of the Eurasian Basin since the Oligocene. This resulted in the activation of the northeastern faults in the region with the same orientation as the transform faults of Gakkel Ridge spreading zone, which supports the active evolution of this region at the present stage.
