  9. Iron-Nickel-Sulfur-Carbon System Under High Pressure, With Implications To Earth’S Mantle

    Zhang, Zhou2016

    Fe-Ni-S-C phases are accessory phases in the Earth’s mantle, but carry important geochemical and geophysical implications. According to their chemical behavior, Fe-Ni-S-C phases preferentially store siderophile and chalcophile elements (and potentially noble gases). Physically, Fe-Ni-S-C phases …
