英文摘要 | The chemical weathering of sulfide-bearing rocks can result in the dissolution of carbonate rocks leading to degassing of to the atmosphere. While this process has been argued to be a significant geologic source of , it also perturbs the geological cycles of oxygen and sulfur, triggering a cascade of geochemical feedbacks. Using a numerical model of geochemical cycles and climate, we found that due to feedbacks on atmospheric oxygen associated with the organic carbon cycle, an increase of sulfide weathering leads to a limited source of followed by a longer sink of . This result is due to the stoichiometry of sulfide weathering where more is consumed than is released. If sulfide weathering increases progressively on a geological timescale, the duration of the carbon source is extended, but its magnitude is negligible before it becomes a carbon sink. |
