Isotope geochemistry in Postojna Cave

Karst terrain is complex and it is difficult to understand the processes that are in course in this system composed of distinctive hydrology and specific landforms. Slovenia is a classic Karst area with prevailing limestone and dolomite deposits. Several thousands of caves of different dimensions have been found in Slovenia. Postojna Cave was chosen for sample collection. Therefpre we expect this work to be a detailed study of carbon isotope transfer in the Karst, enabling us to see how the Karst can record environmental changes. This study was performed by measuring 13C and 14C contents in dofferent components formed in the Karst: surface air, soil CO2, organic matter, dripping water at different depths, cave air and recent cave deposits (stalagmites).
