Zusammenfassung

Der Autor untersuchte zahlreiche Beispiele gleichachsiger Wiederfaltungen in dem Moinian der Schottischen Nordwesthochlande. Diese Art Parallelismus der Faltenachsen ist nicht eine Folge der Fortsetzung einer einzigen Bewegungsphase, sondern folgte aus der Überprägung der beiden Flügel der vorhandenen Falte einer späteren Faltung. Man kommt zu dem Schluß, daß die Gleichartigkeit auf eine starke flexurelle Komponente der überprägenden Spätfaltung zurückzuführen ist.

Abstract

The author has observed many examples of coaxial refolding in the Moinian rocks of the North-West Highlands of Scotland. This coaxial nature of refolding is not the result of the continuation of a single movement phase, but developed where a later fold refolded both limbs of an earlier fold. It is concluded that the coaxiality results from a strong flexural component in the later folding.

Résumé

Nous avons observé plusieurs examples de replissement coaxial dans les roches Moinianes des hautes montagnes Nord-Ouest Ecosse. Les replissements co-axials ne se forment pas par la suite d'un seul mouvement, mais se développent où un pli postérieur replie les deux flancs de raccordement d'un pli antérieur. Nous constatons que la co-axialité résulte d'un composant de flexion très forte dans les plissements postérieurs.
