(IF 4.64 [2018]; Q1) International audience Hyperspectral core logging is a rapid and non-destructive technique in palaeolimnology.The technique is able to track lacustrine sediment sources.Environmental changes in the catchment-to-lake sedimentation and spatial sources are identified.This new method enables the fingerprinting of sedimentary sources with and/or without field samples.Data calibration allows reconstructing total organic carbon concentrations on several cores, at an unprecedented resolution.
