Sulfidation Reaction Mechanisms of Olivine and Diopside at Mercury's Reducing Conditions

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 surfa...

The SiO 2 abundance on the surfaces of the Moon and Mercury

The SiO2 abundance on rocky planetary surfaces is a key indicator for planetary crust composition and magmatic evolution. The Christiansen Feature (CF) in the mid-infrared provides a mineralogically grounded proxy for the abundance of SiO2. Here, we present a new experimental cal...
