4 answers
Magmas exhibit higher solubility of water at higher pressures due to various factors. Mafic magmas with elevated alkali concentrations can dissolve more H2O and CO2, contributing to explosive eruptions. Water solubility in magmas is significantly influenced by bulk composition, with felsic magmas like rhyolite and andesite having greater water solubility than basalt melts. At low pressures, gases in liquids follow Henry's law, but at higher pressures, solubility levels off, with methane in water showing a marked increase in solubility above 1 GPa. Additionally, alkali basalts dissolve more water at pressures above 1 kbar compared to mid-ocean ridge basalts, with a simple empirical model derived to predict water solubility in basalts of varying alkalinity and fO2.What is nuclear energy?
