From: Accumulation of radiocarbon in ancient landscapes: A small but significant input of unknown origin
The relationship between sampling depth and the modelled percent of modern carbon in two Oligocene (28–33 Ma) paleosol profiles. (A), Turtle Cove paleosol; (B) Lakim paleosol (note only four samples were considered). Uncertainties for sampling depth (± 5 cm) and propagated error of model predictions for percent modern carbon (± 0.19%) are shown for each profile.
