Cios poszariażowy w strukturach reglowych rejonu Czerwonej Przełęczy

Abstract

Jointing of post-nappic age In the Sub-tatric series of The Tatra MtsDetailed investigations of tectonic slices within the sub-tatric (Kriżna) nappe in the area of Mt. Mała Świnica and Czerwona Pass, near Zakopane, Tatra Mts (cf. Fig. 1), revealed a phenomenon of consequent (unidirectional) rotation of these structures. The slices occurring here in the superposition (Fig. 2) underwent rotation along the surfaces of overthrusting. Particular members of tectonic units, which contact with one another along these surfaces, exhibit significant discrepancy. Rotation of successive, increasingly higher structures proceeded generally in anticlock-wise direction (Fig. 5), which is revealed by the analysis of statistical orientation of bedding (cf. Fig. 3). The majority of joint fractures (Fig. 4) are characterized by a consistency of directions in all units (NE-SW and NW -BE), independently of their rotation. It therefore appears, these fractures came into being after the phase of nappe transport, presumably during the uplift of the Tatra massif in the Savian tectonic phase (Miocene).
