On calculation of total neotectonic amplitudes considering the World Ocean level changes

Abstract

Total amplitudes of neotectonic movements are usually calculated without taking into consideration the Cenozoic lowering of the World Ocean level, which results in grave errors in views on tectonics and geomorphology, as the value of the lowering is about few hundred meters (no matter what lower limit of the Cenozoic stage is assumed). The author introduced a correction which he used for neotectonic mapping of the Siberian Platform, Using the correction, the vast area of neotectonic down warping (about half of the whole platform area) has been contoured, which is both of applied and certain theoretical importance. Application of the proposed methods to other plain areas may give similar results.
