Fig. 3: Compositional differences between mineral surfaces with OM attached and those that are exposed.

From: Minerals provide divergent protection to carbon- and nitrogen-rich organic matter in fluvial sediments

Fig. 3

a, b NanoSIMS imaging showing the distribution of Si/Al ratios across mineral particle surfaces. c, d NanoSIMS imaging illustrating Si/Fe distribution across mineral particle surfaces. Yellow circles highlight mineral surfaces where OM accumulation occurs (Mode I), while unmarked areas represent exposed mineral surfaces without OM attachment. e, f Box plots comparing Si/Al and Si/Fe ratios between OM-attached and exposed mineral surfaces. The whiskers depict 10–90% range, while the boxes represent the range 25–75% interquartile range, with the median indicated by the central line.
