Measuring and evaluating colorimetric properties of samples from loess-paleosol sequences. [PDF]
MethodsX, 2023 Colorimetric measurements are valuable in studying paleoenvironmental changes in sediment archives such as loess-paleosol sequences. These measurements allow for the identification of climate-sensitive minerals such as hematite, goethite, and secondary carbonates, as well as the observation of stratigraphic changes influenced by paleoclimate variations.
