LOCAL GEODYNAMICS OF NORTHERN SAKHALIN BASED ON RESULTS OF THE ANALYSIS OF LINEAMENTS

Abstract

Sakhalin Island attracts the attention of geologists owing to its location at the boundary of the Sea of Okhotsk and Amur lithospheric plates expressed in a series of diverse faults [2, 3]. According to, the near-horizontal compression, which promotes the meridional extension of the island framework, is the major geodynamic force acting in the deep zones of the island. In northern Sakhalin, the horizontal movements are oriented to the northeast and north, the plate boundary is identified as the East Pil’tun Fault, and its northern extension manifested as the Ekhabi–Pil’tun and Langry strike-slip faults.
