Recurrence times of siderite layers of FB2001 drill core from Messel

Description: To investigate variability and drivers of extreme precipitation events under high greenhouse gas concentrations prevalent during the Eocene we computed recurrence times of Fe/Ti peaks in the XRF scanning record of FB2001, reflecting siderite layers that are interpreted to reflect strong precipitation events. Fe/Ti-peaks were detected based on a peak-detection algorithm, followed by counting over a sliding window. Recurrence times were calculated based on the number of Fe/Ti peaks per 5 ka window. Upper and lower boundaries of recurrence times are calculated based on bootstrapping. The record covers the period 47.66 to 47.22 Ma
