Abstract. Pb has been used for more than two decades to provide the geochronology of annually deposited sediments and to construct pollution histories. Evidence from some lakes suggests that this radionuclide may be adequately mobile to compromise dating reliability. Dating of sediment cores using lead +61 2 [email protected] jsnowcarpenter.com The geochronology of recent sediment materials can be determined by the Pb dating method. Applications are in the areas of Late Quaternary geochronology, sedimentology and biochronology. Capability Selections.

The Pb (lead) method performs best in rela- tively quiet deposition areas such as marsh lands (Ref. 9), bays, lakes (Ref. 4) and the backwaters of river. lead dating The most common isotope of uranium ( U) decays via a series of fifteen intermediate radioactive daughters and eventually ends up as a stable isotope of lead ( Pb). One of the intermediate daughters is the radioactive gas radon ( Rn).

Description:Lead Geochronology - Lead (Pb) geochronology is an isotopic age determination method that is based on the radioactive decay of Rn (radon) and Pb. The radiogenic half-life of -Pb is in the range of years, making it an ideal tracer for late Quaternary geochronology. Thus Goldberg developed the first principles of the Pb dating method, which was soon followed by a paper by Crozaz et al., who examined accumulation history of Antarctic snow using Pb. Shortly thereafter, Koide et al. (, ) adapted this technique to unravel sediment deposition and accumulation records in deep-sea environments. Current $$^{}$$ Pb dating models do not use a proper statistical framework and provide poor estimates of the uncertainties. Here, we develop a new model for $$^{}$$ Pb dating, where ages and values of supported and unsupported $$^{}$$ Pb form part of the parameters.
