Abstract
Volatile interactions with magmas are the cause of many volcanic and plutonic phenomena and volatiles play a central role in the origin and evolution of volcanic and plutonic rocks. In the experimental investigation of silicate melts, volatiles have been used as probes of melt structure and chemistry. The purpose of this paper is to consider which volatiles are important in magma systems, to illustrate effects of pressure, temperature, and oxygen activity on the relative abundances of volatiles, review the experimental data available on their solubilities in melts, and finally to consider some mechanisms for the solution of CO2 and sulfur in silicate melts. Before beginning these tasks, it will be useful to define our subject.
