Detailed analytical results for turbidite T25 (207.0–212.0 cm depth in PC04): a photograph, b X-ray fluorescence image, c grain size analysis (mean grain diameter, percentage sand, and grain size distribution) of 0.5 cm-thick samples, d Ca/Fe ratios, e Zr/Rb ratios, and f Ca/Fe vs. Zr/Rb. Raw data (thick gray line curve) and 5-point running averages (black dots) are shown in d and e. Upward-coarsening then upward-fining trends from A to D in T25 show good correlation with the Ca/Fe and Zr/Rb variations. The highest Ca/Fe (C) and Zr/Rb values (B) are slightly offset, which can be observed as a loop in (f)
