  • Elemental and stable isotope variations in the Cretaceous-Tertiary boundary sediments from the Soča Valley, NW Slovenia
    Dolenec, Tadej ; Pavšič, Jernej
    Oxygen and carbon stable isotopes and 25 elements were determined in the undisturbed K/T boundary profile of a flysch succession in the Soča Valley, Slovenia. The elemental enrichment and stable ... isotope anomalies are not confined strictly to the biostratigraphically defined K/T boundary. The relataively weak metal enrichment, which is probably due to the high sedimentation rate at the time of deposition of the K/T transition sequence, was found in a clayey layer and in the boundary clayey mar] 15 cm and 5 cm above the boundary, while the negataive shift in ▫$\delta^{18}O$▫ and ▫$\delta^13C$▫ of carbonataes was restricted to the basal part of the boundary clayey marl, approximately 5aa cm below the boundary. It is postulated that elemental and isotopic anomalies are probably related to the supposed, so fat poorly investigated impact of an extraterrestial body in the Gorski Kotar area of Croatia.
