- Abstract
The study area is located between Hrušovo and Striežovce villages in the Rimavská Sobota district and is characterized by the occurrence of anchimetamorphosed siliciclastic, carbonate and pelagic deposits. This structure was differently interpreted in the past, when these rocks were included into either the Meliata or Turňa tectonic units. Based on our research we can consider that the sedimentary succession belongs to the Turňa Unit. The lithostratigraphy of the succession is formed of synsedimentary breccias, which later pass into the deep-water sediments during the Middle Triassic. We interpret the breccias as a reflection of the Pelsonian break-off of the Meliata Ocean (synrift sedimentary breccias). The breccias are followed by the phyllitic black shales sedimentation, and are considered to represent the Dvorníky Member, indicating deeper-water sedimentation in comparison with the remaining parts of the Slovenská skala nappe. The Upper Triassic sequence is predominantly represented by cherty limestone, and the younger rocks as Norian are not known in the area. Paleogeographically, it can be assumed that the study area was located somewhere between the Meliata and Turňa sedimentation area. Based on the aforementioned data, it is possible to interpret the study area as the Striežovce syncline, which is the part of the synclinal-anticlinal structure of the Slovenská skala nappe.
