The correlations between ΣHMW n-alkanes concentration (ng/g Sed) vs. (a) Mean grain-size (φ); (b) TOC (w/w %); HMW n-alkanes CPI vs. (c) Mean grain-size (φ); (d) TOC (w/w %); and (e) TOC (w/w %) vs mean grain-size (φ). All plots show linear regression line and one standard error in grey for all data. (φ = −log2 (D/D₀), where D is the diameter of the sample in mm and D₀ is the reference constant 1 mm).
