Article Synopsis
- * Research in Italy's central Apennines measures how different heat flow and crust thickness influence carbon fluxes from weathering, metamorphism, and carbonate melting.
- * Findings indicate that at certain depths and heat levels, emissions from the crust greatly exceed those from near-surface weathering, suggesting tectonic processes play a crucial role in regulating the inorganic carbon cycle.
Biogeochemical reactions modulate the chemical composition of the oceans and atmosphere, providing feedbacks that sustain planetary habitability over geological time. Here, we mathematically evaluate a suite of biogeochemical processes to identify combinations of reactions that stabilize atmospheric carbon dioxide by balancing fluxes of chemical species among the ocean, atmosphere, and geosphere. Unlike prior modeling efforts, this approach does not prescribe functional relationships between the rates of biogeochemical processes and environmental conditions.
