Tektogeneza Alp francuskich w świetle teorii spływów growitacyjnych i próba zastosowania tej teorii w tektogenezie Karpat centralnych

Abstract

TEOTOGENESIS OF THE FRENCH ALPS IN THE LIGHT 0F THE THEORY OF GRAVITY FLOW AGE, AND ATTEMPT AT APPLYING THIS THEORY IN THE TECTOGENESIS OF THE CENTRAL CARPATHIANSHer studies at the Geological Section of the Department of Sciences at the University of Grenoble enabled the author to familiarize herself with the theory of gravity flowage to which French scientists ascribe thectogenesis of the Alps. The author presents this problem with particular attention paid to the conceptions voiced by M. Gignoux.As an example she subsequently discusses, on the basis of the theory of gravity flowage, the tectonics of some parts of the French Alps she visited (the region of Grenoble, the Aravis mountain chain, the flysch nappe of l'Embrunais-Ubaye). On this basis the author attempts to show an analogy between the tectogenesis of the Alps and that of the Central Carpathians.Thus she assumes the migration of a geotumour from S to N which caused a successive shifting - also from S to N - of the overthrusted subtatric series, then the hightatric series and, ultimately, the Carpathian flysch.The theory of gravity flowage, applied to the tectogenesis of the Carpathians, plausibly explains such features as tectonic compensations, loosenings between complexes differing mechanically, an active part played by rigid series, such as limestones, with regard to softer series like shales.
