摘　　要：A water-rich global magma ocean(MO)likely existed in the early Hadean eon and subsequently cooled and solidified.While water is an oxidant and is known to fundamentally affect liquid crystallization,the role of primordial water during the MO crystallization stage has rarely been considered.Recent breakthroughs in water-mineral chemistry suggest that the solidification of a hydrous MO may favor the formation of pyrite-type(Py-)(Mg_(1-x),Fe_(x))O_(2).
