The paleobotanical anlysis was supplemented by 19 radiocarbon dates, however the resolution of the dating was low and the dated samples were mostly taken from the depth below 1 m (Latałowa and Nalepka, 1987). The fen is oblong, about 1000 m long and 500 m wide.
Radiometric dating 210pb
A secondary cosmic ray neutron of sufficient energy striking a common nitrogen 14 nucleus can force it to eject a proton.
C like they absorb other isotopes of carbon — through the respiration of carbon dioxide — and then use this carbon to produce sugars, fats, proteins, and vitamins.
This depth corresponds to the modelled age intervals 355–300 BC (17.4%) and 205–45 BC (50.7%).
It has been shown (Shotyk, 1996) that peat sediments are important archives for the reconstruction of the past environmental changes, induced naturally and by human activity.
This rare, unstable isotope is produced from ordinary nitrogen 14.
