a Proportion of plant macrofossils. b δ13C values of C29 and C31 n-alkanes. c Hopanoid flux35. d Total concentration of bacterial C27β, C29βα, C29ββ, C30ββ, C31αβ, and C31ββ hopanes. e Concentration of fungal C18:2ω6,9 fatty acid. f δ13C of C31αβ hopane. g The carbon isotope offset (εhopane/bulk) between δ13C of C31αβ hopane and bulk organic carbon. h δ2H of C31αβ hopane. i The hydrogen isotope fractionation (εhopane/water) between C31αβ hopane and source precipitation water. j Proportion of carbohydrates. k Proportion of aromatics. l Total organic carbon content35. m Apparent carbon accumulation rate (aCAR)35. n Bulk density35. The gray shading marks the 8–6 ka period of woody plant expansion.
