Extended Data Fig. 7: Analysis of sensitivity to diagenetic model parameters.
From: Reverse weathering as a long-term stabilizer of marine pH and planetary climate
Baseline conditions (green) are the deep-sea environment, with marine [H4SiO4] = 2.21 mM and marine DIC = 0.030 M. Shown are sensitivity to sedimentation rate ω (yr−1), diffusion coefficient of [H4SiO4] (cm2 yr−1), organic matter rate constant korg (yr−1), reverse-weathering rate constant krw (yr−1), calcite rate constant kcalc (mol cm−3 yr−1) and the efficiency of water column P scavenging.
