Upper CArboniferous to Lower Triassic Carbon Isotope Stratigraphy of the Western Tethys: Evidence from the Southern Alps-Karavanke Mountains and Julian Alps, Slovenia

Abstract

The carbon isotope stratigraphy of selected stratigraphic sections from the Karavanke Mountains (Dol~anova soteska, Koutnik Creek, Brsnina) and from the eastern and southern part of the Julian Alps (Strata Hill, Zirovski vrh, Idrijca Valley) spanning an aproximately 1600 m thick stratigraphic interval ranging from Upper Carboniferous to Lower Triassic was used to examine their depositional environment, as well as the changes associated with shifts in carbon isotopes. For this purpose carbon isotope analyses were performed on more than 250 limestone, dolomite and pedogenic carbonate samples from different stratigraphic intervals.
