Marine carbonate precipitation
Uncertainty
Eventually, the formation and burial of carbonate minerals will release CO₂ stored by mineral weathering. This process counteracts most or all of the carbon storage associated with weathering carbonate rock, and around half of the storage associated with silicate rock weathering. The carbonate precipitation process occurs slowly and is unlikely to have a significant impact on estimates of carbon storage on decadal to millennial timescales. However on geologic timescales, it is an important process to characterize.

First release. Added this component to explicitly reflect Marine carbonate precipitation rather than implying it in DIC residence time. These edits occured as part of a broader update of the Enhanced Weathering pathway.
