Does the Tethys Begin to Open Again? Late Cenozoic Tectonomagmatic Activization of the Eurasia from Petrological and Geomechanical Points of View

Features of Caucasian Segment of the Alpine-Himalayan Convergence Zone: Geological, Volcanological, Neotectonical, and Geophysical Data

“…Isotopic and geochemical data suggest that origin of magmatism of suprasubduction type associated with interaction between a mantle plume head and continental crust material (Lebedev et al, 2006;2011;Chugaev et al, 2012). Judging by the fact that the orientation of East-Anatolian-Caucasian zone, where joined Anatolian-Caucasian and CaucasianElburssian arcs, practically coincides with the zone of syntaxis, i.e.…”

“…1) is the part of the largest Alpine-Himalayan collision zone, stretching out for 16,000 kilometers across Eurasia from the Western Mediterranean to the Western Pacific. In geological terms, it is represented by huge area of the Trans-Eurasian Belt (TEB) of Late Cenozoic activation, which was formed after the closure of the MesozoicEarly Cenozoic ocean Neotetis (Sharkov, 2011). TEB is characterized by powerful modern processes of mountain building, appearance of rift structures, numerous intraplate basaltic lava plateaus and chains of intracontinental andesite-latite volcanic arcs that trace suture zone of continental plates collision.…”
