a, b, Surface coating OM (mode I) and pore occluded OM (mode II) are circled by red and green lines respectively. c-f, Spatial distribution of C/N and δ13C composition of the surface coating OM (mode I, c, e) and pore occluded OM (mode II, d, f). g, h, Box plots of C/N (g) and δ13C (h) differences between the OM preserved via two modes: boxes represent the range 25–75% with medians as the middle lines, and whiskers represent standard deviation.
