  • Macroscopic paleokarstic features in Upper Cretaceous limestones of the Adriatic-Dinaric carbonate platform (SW Slovenia)
    Otoničar, Bojan
    The investigated area of SW Slovenia (Matarsko Podolje) in a paleogeographical sense belongs to the Adriatic-Dinaric carbonate platform. The lower boundary of the youngest (terminal) megasequence of ... the platform is represented by regional disconformity that was caused by Late Cretaceous and Early Paleogene emersion of the carbonate platform. We can find evidence for emersion in surface and subsurface paleokarstic phenomena. For both paleokarstic types dissolutional morphological features, either covered or infilled by different sediments, paleosols and cements (speleothems), are characteristic. Paleokarst surface is irregular or undulated and could penetrate into underlying limestones through subcutaneous dissolutional pits and pipes. Surface paleokarst features are marked by different porosity types (vuggy, channel and cavern porosity). There is obvious lateral variability in development of the surface and subsurface paleokarstic features. Facies variabilities are also found in limestones below and above disconformity.
