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.

西泰米尔的新构造构造

摘要

对现代浮雕的结构地貌分析使我们能够揭示西泰米尔的最新结构中的模式,并显示出结构形式的剪切水平位移的重要性,以及先前在某些地区对浮雕形成的推力的表现。自渐新世以来,欧亚盆地的开放一直控制着北极地区的新构造演化。这导致了该地区东北断裂的活化,其方向与Gakkel Ridge扩张带的转换断裂方向相同,这支持了该地区在现阶段的活跃演化。
