Keywords: Alpine-Himalayan-Indonesian mobile belt, paleoocean Tethys, oroclinal closure, epigeosynclinal structure
Аnnotation: Based on the available geological and geodetic data, it is established that the structures of the Alpine-Himalayan-Indonesian mobile belt are oroclinally (horseshoe-shaped) closed at its Western and Eastern extremities. In the West, from the Atlantic ocean, this closure is represented as the Bet-RIF arc, and in the East, from the Pacific ocean, as the Band and Mindanao arcs. These closures mean that there is no structural connection between the mobile belt under discussion and the Atlantic and Pacific oceans, respectively. Thus, the existing pleittectonic reconstructions, according to which the ancient paleoocean Tethys was a wide Bay of the Pacific ocean, which (Bay) in the West was connected to the Atlantic ocean «Wide Tethys») not true. The Alpine-Himalayan-Indonesian mobile belt has to be considered as an epigeosynclinal rather than an epioceanic structure.
