| Abstract: | The rotary formation mechanism of various central-type geological structures functioning in the strike-slip fault systems of the West Pacific continent-ocean transition zone is considered. This mechanism explains many tectonomagmatic processes and is confirmed by geological, geophysical, and geomorphological studies. At the same time, it is not the only possible mechanism. Examples of magmatogenic central-type ring and vortical structures in the Japan Sea segment of the West Pacific continent-ocean transition zone are given. In our opinion, the proposed geodynamic model is inscribed into the paradigm of tectonic delamination of the lithosphere developed by Yu.M. Pushcharovsky. |
