A new interpretation of depth-age profiles
journal contributionposted on 2023-06-07, 21:34 authored by P D Townsend, R Parish, AP Rowlands
Dosimetry and other techniques provide depth¿age profiles in materials as diverse as sediments and ice. A frequent characteristic feature of these plots is a non-linear curve with a foreshortened depth scale. Whilst the age analyses from the dosimetry do not present a problem, many authors have made subsequent assumptions on the basis of the curve shape with respect to climate and environmental changes. Such claims should be strongly questioned, as by using a modelwhich includes the effects of compaction, most of the original curves transform into linear plots corresponding to constant depositional rates. The corrections and the implications for models of climate change are discussed.
