Abstract

There are several geodynamic models of the Central Asian Orogenic Belt (CAOB) development [Sengor et al., 1993, Zorin, 1999; Parfenov et al., 1999, 2003; Willem et al., 2012; and others]. The Mongol-Okhotsk Orogenic Belt (MOB) represents important part of CAOB. All geodymanic models of Late Riphean to Paleozoic structures of CAOB emphasize significance of subduction processes along Northern Asian craton margin at that time. Collage of CAOB terrains formed as a result of accretion of island arc, accretionary wedge, turbidite, and continental margin terrains to the Siberian paleocontinent.

Highlights

  • There are several geodynamic models of the Central Asian Orogenic Belt (CAOB) development [Şengör et al, 1993, Zorin, 1999; Parfenov et al, 1999, 2003; Willem et al, 2012; and others]

  • Collage of CAOB terrains formed as a result of accretion of island arc, accretionary wedge, turbidite, and continental margin terrains to the Siberian paleocontinent

  • Formation of large volumes of the granite magmas within orogenic belts is often related to widespread terrain displacement, when the settings of active continental margin and collision turn into transform margin of lithospheric plates
