14C AMS dates of charcoal from Aksay Pond, NW China

This dataset contains the charcoal-derived 14C record preserved in the sediments deposited in a fault-bounded sag pond in the southern Altai Mountains to explore the fire history of the region. Thirty-two charcoal/wood fragments and bulk organic samples were collected from the pond and analysed at the Scottish Universities Environmental Research Centre (SUERC) for 14C Accelerated Mass Spectrometry (AMS) radiocarbon dating. Only charcoal dates are used and reported in this study. 14C AMS dates were calibrated using IntCal20 (Reimer et al., 2020). Modern post-bomb fractionated carbon (F14C) results were calibrated, using IntCal20 as the pre-bomb and Northern Hemisphere Zone 1 (Bomb13NH1) as post-bomb calibration sets respectively (Hua et al., 2021), to obtain accurate dates on the post-1950 material.
