The study of morphological transformations in the process of evolution of local geological objects has shown that inverted
anticlines in the platform regions are formed as a result of directed migration of the sagging rate from the centers of geological
objects to their margins. At the initial stage, the highest rates are localized in the central portions of the future anticlines
and then shift outward. At the final stage, the highest rates are confined to the marginal zones, giving rise to the formation
of anticlines. This mechanism explains the occurrence of troughs at the bottom of the positive structures; the regular, oval,
and ellipsoidal morphology of many anticlines; and the high prevalence of regular anticlines over regular synclines. The proposed
model of migration tectogenesis differs substantially from the concept developed by N.S. Shatsky; however, in light of modern
data, his idea of the residual nature of platform anticlines acquires general geological significance.
