The crystallization regime of Mercury’s core controlled by Silicon?
Published on February 22, 2022
Mercury being so close to the Sun, the environment of formation of the planet is considered to be depleted in oxygen, and thus very reducing, leading to the presence of significant quantities of silicon alloyed with iron in its core (Fe-Si alloy). However, the phase diagram of the Fe-FeSi system remained poorly constrained to the high pressure and high temperature conditions prevailing at the center of Mercury
A team of researchers, led mainly by members of IMPMC and ISTerre, have (...)
