Columns from left to right: Core color profile (MSCL- spectrophotometer), grain sizes in %, PC2 of the color reflectance (ref. 15) and scanning XRF results (5 mm resolution) in normalized counts report to the upper x-axis (blue plots and red curve) and are compared to results of quantitative XRF analyses (concentrations in mg/kg) that report to the lower x-axis (red and black squares). Elemental variations from left to right: iron (Fe), titanium (Ti), potassium (K) (note inverted scale), zirconium (Zr), manganese (Mn), calcium (Ca) (note inverted scale). Episodes on the right axis correspond to environmental episodes in Fig. 2. Proxy values oriented to the right indicate wet conditions; proxy values oriented to the left are indicative for dry conditions.
