Plots of Ca/Fe vs. Zr/Rb for a sedimentary units 1 (black circles) and 2 (blue squares), b hemipelagites (gray circles) and turbidites of sedimentary unit 3 (red triangles), and c 36 individual turbidites (maximum values). Regressions for sedimentary units 1 and 2 are shown as black and blue lines, respectively, in a. Symbol sizes in c represent the thickness of each turbidite bed. Turbidite T25 (red circle, 2.9 cm thick) has the highest Ca/Fe value of all analyzed turbidite beds. Turbidite T27 (green circle) is the thickest observed turbidite bed (4.2 cm). Regressions for turbidites and hemipelagites are shown as red and gray lines, respectively, in c
