Fe2+ is the most abundant iron species in magmas and in many slags. Its structural role in these liquids is poorly understood, largely because of the difficulty of studying melts at high temperatures by direct structural methods. Whether Fe2+ behaves as a network modifier, network former or free-ion complex has not been adequately resolved, yet this is fundamental to understanding the properties of silicate liquids. Also uncharacterized are the structural changes accompanying the melt-to-glass… CONTINUE READING
