    Decoupled sedimentary records of combustion: Causes and implications by Ulrich M. Hanke, Timothy I. Eglinton, Ana L. L. Braun, Christopher M. Reddy, Daniel B. Wiedemeier, Michael W. I. Schmidt

    Published 2016-05-01
    “…We find markedly discordant records for different PyC tracers, particularly during the preindustrial age, implying different origins and modes of supply of sedimentary PyC. In addition to providing new insights into the composition of sedimentary combustion products, this study reveals that elucidation of past combustion processes and development of accurate budgets of PyC production and deposition on local to regional scales requires careful consideration of both source characteristics and transport processes.…”
