THE TECTONIC SETTING AND ORIGIN OF THE SMILNO TECTONIC WINDOW (EASTERN SLOVAKIA)
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2012, Vol 449, Issue 449
Abstract
The Smilno tectonic window is located in eastern Slovakia between Smilno in the west and Nižný Mirošov in the east. Geologically, the Smilno tectonic window occurs in the Magura Unit, within the Racza Subunit. In this area, deposits of the Grybów and Dukla units crop out from under the Magura Unit rocks and occur at the surface. The Dukla Unit section is represented by the Submenilite Formation occurring in the northern part of the window. The upper Grybów Unit is represented by the Menilite Formation and the Krosno Beds. The Smilno window developed as a result of a multi-stage formation of flysch masses in this region. In the earliest stage, flysch masses were displaced over the Makovice Ridge from the south into the graben. The graben was filled mostly with deposits of the Silesian and Dukla units, overlain by the Grybów and Magura units. In the next stage, there was a restructuring of the Makovice Ridge, which extended into the overlying deposits of the Silesian and Dukla units. During the later stage, tectonic deformation spread out into the Grybów and Magura units. Not only discontinuous tectonic deformation, but also the beginnings of folding processes, developed as a result of SW-oriented stress, is observed within them. In the next stage, the SW-oriented stress plays a significant role. It resulted in a shift of the Grybów and Magura units and the top part of the Dukla Unit in relation to the Dukla and Silesian units. The last stage included primarily a shortening and thrusting of the Grybów and Magura units and the top portion of the Dukla Unit. Due to this process, the Magura Unit broke up, and the Grybów and Dukla units, today present in the Smilno window, pierced up to the surface along discontinuity planes. In each case described, the occurrence of a tectonic window within flysch deposits was associated with the presence of a resisting element in the consolidated basement of the Carpathians to the south of the window zone; in the case of the Smilno window, it was the Makovice Ridge.
