Abstract:
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.
