Radiocarbon dating of Hashilan Wetland sediment core, western Iran@en

Eleven samples including organic sediment, seeds, and charcoal fragments were picked from the Hashilan sediment core and submitted to the Beta Analytic Radiocarbon Dating Laboratory, Miami. The AMS 14C dates were calibrated using the Northern Hemisphere terrestrial calibration curve IntCal20 (Reimer et al., 2020). The Bayesian age-depth model was generated using the rbacon package (Blaauw and Christen, 2011) and the RStudio software (R Development Core Team, 2013). The 95% confidence intervals are based on a 2σ range of average iterations.从哈希兰（Hashilan）沉积物岩芯中选取11份样品，涵盖有机沉积物、植物种子与炭屑碎片，随后将其提交至美国迈阿密的Beta分析放射性碳测年实验室（Beta Analytic Radiocarbon Dating Laboratory）。针对加速器质谱（Accelerator Mass Spectrometry, AMS）14C测年结果，采用北半球陆生校正曲线IntCal20（Reimer等，2020）完成校正。本研究通过rbacon程序包（Blaauw与Christen，2011）及RStudio软件（R开发核心团队，2013）构建贝叶斯年龄-深度模型。95%置信区间基于平均迭代的2σ范围确定。
