Carbon Speciation and Solubility in Silicate Melts

open access: yesCarbon in Earth’s Interior, 2020
To improve our understanding of the Earth's global carbon cycle, it is critical to characterize the distribution and storage mechanisms of carbon in silicate melts. Presently, the carbon budget of the deep Earth is not well constrained and is highly model‐dependent.
