Abstract
The problem of a pressure or volume increase due to the vertical redis tribution of two substances with differing compressibilities is consid ered and compared with a previous treatment. Modified expressions for the pressure and volume changes are obtained using the general equatio n of state with constant compressibility. The effects of gas and melt compressibilities, and also of the solubility of gas in floating bubbl es, on pressure and volume changes in magmatic systems are discussed. Very different conclusions from those in the previous treatment are fo und.
