Portable X‐Ray Fluorescence Spectroscopy as a Tool for Cyclostratigraphy [PDF]

Geochemistry, Geophysics, Geosystems, 2019
AbstractCyclostratigraphic studies are used to create relative and high‐resolution time scales for sedimentary successions based on identification of regular cycles in climate proxy data. This method typically requires the construction of long, high‐resolution data sets.
