The model of plate-collisional orogene fails to explain why the uplift zone of an erogenic belt always lies at the inland side of the active continental margin with a certain distance away from the collision zone and why the uplift of the mountain range often happens quite a long time later after the convergence of two continental plates while the regional crust is relatively stable during tbat period. Many investigations have indicated that the dynamic force of mountain range uplift comes from the deep inner earth. Hence to explore the physical and chemical mechanism of the geologic processes in the deep part of the earth and their consequent re-distribution of energy is of key importance to understanding the dynamics of mountain uplift. Some clues have led the authors to associate nuclear reaction occurring in the mantle with the dynamic mechanism of the lithospheric evolution. The geochemical properties of U and Th and other lithophile elements and their behaviours during deep-seated metamorphic processes suggest that the recycling of continental crustal materials into the mantle concomitant with plate subduction may result in U, Th and other lithophile elements as well as carbon (graphite) at the top of the asthenosphere. Theoretical verification and inversion deduction of the remains in the Oklo natural nuclear reactor indicate that at least some of the geologic bodies may have the requisites for the formation of natural graphite nuclear reactors. The off-and-on operation of these reactors in the sub-critical state may provide heat for magmatism in the lithosphere above them, and once the reactors run beyond their critical state, huge nuclear explosion may take place in the deep levels of the earth, giving rise to earthquakes, volcanic eruption and rupturing of the lithosphere. Thereupon a mountain uplift dynamic model has been constructed here to explain the formation of orogenic belts, uplift of the plateau, origin of deep-focus earthquakes and their precursors, as well as the emplacement mechanism of diamonds and their related rocks in the shallow levels of the crust.
