Abstract The paper presents the results of measurements the specific concentration of lead-210 for six peat profiles representing four peat bogs from two regions of Poland and the problem of creating age-depth models. For the construction of age-depth models, it is proposed to use mathematical functions, the best fit to the measured activity. The F-statistics were used as a measure of the match quality. The obtained models are visualized in two ways – showing the age calculated on the basis of direct measurements of activity and indicating points that are the results of the used approximation. Such visualization is important to clearly distinguish the places of the age-depth model that result from the measurements of activity from those places that are the result of the approximation used. This paper proposes and tests the application of activity modelling for the cores shorter than the range of the lead method. The paper also outlines the limitations and potential dangers related to the interpretation of core dating results i) obtained by using the activity approximation resulting in the smoothing of the age-depth profile, and ii) for the cores of a length smaller than the depth of the presence of the unsupported lead. Additionally, the proposed models were compared with the models obtained by using SIT, Mod-Age, OxCal, Clam, and Bacon programs.

一种构建低频采样幼泥炭剖面Pb-210年表的新方法

摘要 本文介绍了代表波兰两个地区的四个泥炭沼泽的六个泥炭剖面的铅 210 特定浓度的测量结果以及创建年龄深度模型的问题。对于年龄深度模型的构建，建议使用最适合测量活动的数学函数。F 统计量被用作匹配质量的度量。获得的模型以两种方式可视化——显示根据活动的直接测量计算的年龄和指示使用近似结果的点。这种可视化对于清楚地区分由活动测量产生的年龄深度模型的位置与作为所使用的近似结果的那些位置很重要。本文提出并测试了活动建模对短于铅法范围的核心的应用。该论文还概述了与岩心测年结果解释相关的局限性和潜在危险 i) 通过使用活动近似获得的年龄深度剖面的平滑，以及 ii) 对于长度小于深度的岩心无支撑铅的存在。此外，将提出的模型与使用 SIT、Mod-Age、OxCal、Clam 和 Bacon 程序获得的模型进行了比较。ii) 对于长度小于无支撑引线存在深度的磁芯。此外，将提出的模型与使用 SIT、Mod-Age、OxCal、Clam 和 Bacon 程序获得的模型进行了比较。ii) 对于长度小于无支撑引线存在深度的磁芯。此外，将提出的模型与使用 SIT、Mod-Age、OxCal、Clam 和 Bacon 程序获得的模型进行了比较。
