Geomorphic indicators of tectonic activity at the Sava folds - Ljubljana basin transition, Tunjice hills, Central SloveniaPezdir, Valentina (Avtor) Vrabec, Marko (Mentor) Szekely, Balazs (Komentor) Tunjice Hillstectonic geomorphologyriverstectonic activityriver sinuosityhypsometric integralTunjice Hills are located on the northwestern edge of Sava folds and represent a syncline structure with a fold axis in W - E direction. The Hills are composed of Miocene rocks. In thesis I investigate whether Quaternary tectonic activity occurs in the area, and whether active deformation can be attributed to the active folding of the Sava folds. I applied tectonic geomorphic methods to streams that flow over Tunjice Hills. I determined differences in sinuosity along the channel and investigated shapes of hypsometric curves and longitudinal stream profiles. I calculated values of hypsometric integrals and concavity parameters of maximal concavity and concavity factor and examined how far maximal concavity point is located from the source of the stream. The results show an increase in sinuosity when the rivers cross faults, at lithological changes, and in vicinity of confluence points. Most actively changed segments of streams are located in the westernmost stream and in central area of Tunjice Hills. Hypsometric curves for streams in the central part of Tunjice Hills have sigmoidal shape with possible tectonic activity in the lower part of the streams. From shape of hypsometric curve and values of hypsometric integral and concavity parameters, tectonic activity is apparent on the fault that runs along the Kamnik stream valley. Hypsometric curves, longitudinal stream profiles and concavity analysis showed that the eastern margin of the Hills is stable and in mature to old erosional stage which was also determined for a stream between westernmost Kamnik stream and central area. Tectonic activity is present on faults that belong to Sava fault zone. There is no indication of active deformation in Sava folds trend.20192019-09-08 07:46:43Magistrsko delo/naloga109800sl
