Raw X-ray fluorescence core scanning (XRF-CS) data of a sediment core from Lake Tepetiltic (Nayarit, Mexico)

DOI

Raw X-ray fluorescence core scanning (XRF-CS) data of sediment core LTp22-1 retrieved from Lake Tepetiltic in April 2022. Scans were performed with a 5 mm step size and 30 seconds dwell time. The analysis yielded the ratio of Compton (incoherent) to Rayleigh (coherent) scattering (Inc/coh) that can be used as an indicator of sediment organic matter content. The measurements extend back to the late 1800s. Ages were estimated using Pb-210 dating and Bayesian age-depth modeling.
