Sulfidation Reaction Mechanisms of Olivine and Diopside at Mercury's Reducing Conditions
Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.Abstract The surface of Mercury contains elevated amounts of sulfur of up to 4 wt.%. Volcanic degassing of S from the interior of the planet could have initiated sulfidation reactions between the degassed S and surface materials in the planet's past, leading to the observed surface S enrichment.
