Tectonic movements, structures and morphostructures of platformian plains

Abstract

There are two tendencies in solving of the problem of tectonic structures manifestation in the present-day topography: firstly, acceptance of notion on autonomous (not inherited) character of neotectonic movements instead of ideas that the movement pattern being completely inherited and everywhere manifested in topography, secondly, development of ideas of inherited neotectonic movements playing important role in development of Pre-Cenozoic structures. There are data on presence and absence of connection between relief and structures which require to assume that neotectonics consist of both inherited and autonomous components. The acceptance of the simultaneous and general manifestation of inherited and autonomous movements in topography and structure allows to identify morphostructure as a part of the Earth's surf ace. Inherited component in neotectogenesis which controls efficiency of structural geomorphological methods application to structures prospecting increases along with transition: I) from folded to fault-block tectogenesis, 2) from small to large structures and from ancient to young ones, 3) towards marginal zones of plates where Sedimentary mantle becomes thinner, general tendency to subsidence persisting at central parts.
