Reinterpretácia vyskytov meliatika v?oblasti Brádna a?Ráko?a (Revúcka vrchovina, Západné Karpaty)

摘要

We present results of reinvestigation of two areas where, according to published geological maps, the Meliatic rocks should occur as tectonic slices inserted between the Turnaic Slovenská skala Nappe and the underlying Palaeozoic complexes of the Gemericum. However, these occurrences were not confirmed by our research. Instead, we document a continuous, though overturned, Lower–Middle Triassic succession of the Turnaicum in the area of Ráko? Village, since no typical Meliatic rocks were found there. Similarly, the supposed slivers of the Meliatic B?rka Nappe near Brádno Village are reinterpreted as cataclastic tectonic breccias (rauhwackes). The breccias are dominantly composed of carbonate fragments with small portion of siliciclastic material derived from the overriding Turnaic thrust sheet. They likely formed during its nappe emplacement over the underlying Gemericum.
