Dislocations of the cretaceous and cenozoic complexes of the northern part of the West Sakhalin Terrane

Resumo

The contemporary structure of the West Sakhalin Terrane started to form in the Pleistocene and the process of its formation continues up to now in a setting of ENE (60°–90°) shortening. Evidence of the preceding NE (30°–45°) compression was revealed during the study. This compression prevailed in the Eocene–Pliocene. Under the settings of NE (30°–45°) compression, dextral displacements occurred along the West Sakhalin and Tym’–Poronai fault systems, bounding the West Sakhalin Terrane.
