Abstract (in english)
   This study presents detailed lithostratigraphy and stable carbon and nitrogen isotopic variations in a 520-cm-long sediment core from a cirque basin in the Labský důl Valley, Krkonoše Mountains, Czech Republic. Detailed study of the core reveals five major periods of sedimentation during the last 7600 years: silt and sand deposition during ~7.6-5.1 ka cal BP, Sphagnum peat accumulation during ~5.1-4.0 ka cal BP, sandy silt and sand during ~4.0-2.8 ka cal BP, raised peat bog during ~2.8-2.0 ka cal BP (Sphagnum peat), and sedimentation of sandy silt since ~2.0 ka cal BP. We conclude that the primary stable isotope variations are not preserved in the layers where significant correlation between d15N and C:N ratio is observed. The relatively small d13C variation in the uppermost Sphagnum peat layer suggests stable temperature during ~2.8-2.0 ka cal BP.
