Correction to: Nature Geoscience https://doi.org/10.1038/s41561-021-00815-z, published online 20 September 2021.

In the version of this article originally published, there was an error in equation (15). Originally reading “Creleased = Reflux × (OCsd/Resd) × 𝑓C𝑓graphite”, the equation has been amended to read “Creleased = Reflux × (OCsd/Resd) × 𝑓C × (1 −𝑓graphite).”

The change has been made to the HTML and PDF versions of the article.
