The measured parameters of the dolines were used for...
The principle of authigenic 10Be/9Be dating method is similar to any other radiometric dating method which utilizes the equation N=N0 e-λt. However, the different source of the isotopes 9Be (from weathering of rock massifs) and 10Be (from atmosphere, through spallation reaction) brings some difficulties in direct application of the authigenic 10Be/...
The kinematic evolution of the Western Carpathian and Eastern Alpine orogenic belts shows similarities but also differences. In both orogens Eo-Alpine (Cretaceous) deformation is prevalent in the internal southeastern part, whereas nappe stacking in the northern frontal part occurred during the Neo-Alpine (Cenozoic) phase, which caused also back th...
