  • Mesozoic carbonate rocks in Slovenia : a case study for isotope composition
    Ogorelec, Bojan ; Pezdič, Jože ; Dolenec, Tadej
    Carbonate rocks occupy more than two thirds of the Slovenian territory. They are developed as limestones and dolomites, ranging in the age from Late Permian to Late Cretaceous. Studied carbonate ... rocks were deposited in various sedimentary environments: shallow shelf and littoral, restricted shelf, lagoons and deeper basins. The most important diagenetic processes influencingisotopic composition of rocks were dolomitisation, dedolomitisation, and phreatic and vadose cementation. The present study is based on analysis of nearly 300 rock samples from diffrent tectonic units. Isotopic compositions of oxygen ranges from [delta] [uper] 18 O = +34 %o in dolomites to the lowest detected calue of +21 %o obtained for limestones, and [delta] [uper] 13 C ranges from -5 %o to +2 %o, depending on the influence of vadose processes.
