Reviews in mineralogy. Volume 25. Oxide minerals: petrologic and magnetic significance / Обзор по минералогии. Том 25. Оксиды: петрология и магнитные свойства

When discussing the stability of iron oxides, one must invariably deal with oxygen fugacity as a variable. To many geophysicists the importance of this variable in determining the stability and composition of oxides is not immediately apparent. Indeed, even within the petrologic community there are many misconceptions about what oxygen fugacity is and how it applies to rocks. The purpose of this chapter is to introduce the concept of oxygen fugacity so that later discussions within this book that use oxygen fugacity as a variable will be more comprehensible. <...>
