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.-104.69016721.277661Lake Tepetiltic, Nayarit, MexicoFonds de la Recherche Scientifiquehttps://doi.org/10.13039/501100002661PDR T.0079.21Holocene Mexican Crater Lakes and Climate (HolMeCl)
