Radiocarbon dates of sediment slices from the MexiDrill core of Lake Chalco, Mexico (40-0 kcal BP) (NERC Grant NE/S009035/1)
The MexiDrill core was dated using a range of methods, including radiocarbon. Samples of sediment were pretreated (acid-only) at the 14CHRONO Centre according to established protocol, and measured using Accelerator Mass Spectrometry (AMS). The plain-text file lists the uncalibrated AMS radiocarbon dates, with the following columns: UBA ID, date submitted, MexiDrill sample ID, radiocarbon age, and lab error.
