| Abstract: | The Himalaya is a frontal part of an intracontinental collision system connected with an approach of Asia and Hindustan. This approach takes place in the “cold” sector of the Earth (global seismic tomography data) expressed by the geoid surface's depression. This depression is limited from east and west by lineaments (linear slopes the geoid surface) penetrated up to the core\|mantle boundary. It consists of an Asian low step and the Indian ocean minimum of the geoid surface stipulated by gigantic “cold” crust\|mantle blocks. The Indian ocean crust\|mantle block has 1500km vertical sizes and moves northward, and displaces the Tibet—Himalaya fragment of the Mediterranean mobile belt to the same direction more than 1000km. The Himalaya is on the contact of the Asian and the Indian ocean crust\|mantle blocks. The lithospheric plates' displacements add the approach of gigantic “cold” crust\|mantle blocks. |
