Fig. 10

Organic geochemistry results from hemipelagites (gray dots) and turbidites (red triangles) are grouped based on their stable carbon isotopic compositions (δ13C) and total organic carbon (TOC) and nitrogen (TN) contents. a TN vs. TOC, b δ13C vs. TOC/TN, and c δ13C vs. TOC/TN shown at a broader scale and interpreted in terms of particulate organic carbon (POC) provenance after Lamb et al. (2006). C3 and C4 plants represent the fields of terrestrial plants
