Abstract
The capacity of magmatic components such as dissolved or precipitated ferrous and ferric iron compounds and water to control the oxygen fugacity of magmas is treated from a theoretical standpoint. Stoichiometric calculations indicate that in relatively anhydrous magmas, such as those of the Skaergaard j complex, the oxygen fugacity is determined by the reaction of ferrous and ferric iron if these are abundant relative to the quantity of dissolved water. However if the quantity of water is high relative to iron, as in the calc-alkali batholiths, the oxygen fugacity is likelyto be determined by the dissolved water of a given H, D/H2 ratio and by the tendency of H 20 to react with the Si-O-Si bridges of the si_cate melt.
