Abstract

The solution and states of volatile in magma, as well as the constraints on the solubility of H2O in melts, are discussed in this paper. The significance of volatile for magma evolution and its petrogenesis is considered. H2O dissolved in magma can influence the crystallization consequence and the evolution trace of melts. For water-contained basalt magma, iron oxides crystallize early and separate from SiO2 and alkali-rich components, which convert basalt magma to Fe-deficient calc-alkaline magma, but to more-H2O basalt magma, magnetite can not precipitate in early stage, so it evolves to be Fe-rich, medium Si content tholeiite. The decompo sit ion of H2O in magma results in high fO2 environment, under which iron oxides precipitated early in the magma evolution.
