Abstract

A concept of global tectogenesis is based on the hypothesis of a continuous mantle melts crystallization in the contact zone between the lithosphere and the "partially melted mantle" during the slow cooling of the Earth. The main premise is the supposition about the dependence of crystallization rate on the mantle melts on pressure, temperature and their composition and, consequently, on the differentiated thickness of the lithosphere on the planet. The process causes a global non-equilibrium in the occurring subterranean Archimedian forces responsible for the formation of regional stress fields, which lead to tectonic collisions. The principal features of the modern tectogenesis are discussed within the frame of a unified approach based on the planetary differentiation of ascending forces influencing the consolidated lithosphere. These features include the mechanisms of formation of enormous folded belts, oceanic ridges and deepwater trenches that comprise the extremely contrasting forms of contemporary relief. The emphasis is made on the recent manifestations of the global tectonic process (seismicity and volcanism).
