AMS 14C dating with characterization by pyrolysis and infrared technology reveal terrestrial organic carbon cycling dynamics (IMAGE)
Caption
The updated pyrolysis system successfully partitions thermally labile and stable organic carbon fractions.
Their AMS 14C age patterns demonstrate terrestrial carbon cycling dynamics that are known only in models.
Their reverse older-younger/identical age patterns exhibit protective preservation under weak respiration.
Their constant younger-older age patterns exhibit selective preservation under intensive organic degradation.
Their identical modern to younger-older age patterns across depth reveal organic carbon fixation dynamics.
