Abstract

V originále

The current state of the Devonian-Carboniferous (D-C) boundary definition is a subject of wide criticzm. Based on the gamma-ray spectrometry, magnetic susceptibility, stable carbon isotope and element (EDXRF) geochemistry were carried out correlations between the most important D-C boundary sections in the Europe. Positive shift of the carbon isotopes, decrease of the Th/U (paleo-redox proxy for lowering of the oxygenation) and consequent increase of the gamma-ray and magnetic susceptibility signal just bellow the D-C boundary are the most distinct correlatable patterns between the majority of the studied sections. Using of the quantitative multi-instrumental methods bring objective correlation and upgrade the former biostratigraphic correlations.
