# Do different lavas have different volcanic volatiles associated with them?

This question was inspired by the question Predicting volcanic eruptions by experimentally proven volatile outgassing observations

Depending on the type of volcano, three types of lava are released by current volcanoes on Earth: basalt, andesite and rhyolite. Given the different compositions of each type of lava are there differences in the ratios of volcanic volatiles $\ce{SO2}$, $\ce{CO2}$ and $\ce{H2O}$ associated with each lava type?

• In the extreme case of carbonatites the volatiles contain a very high level of CO2 and the degassing can have disasterous results, for example Lake Nyos in Cameroon. But I don't have a good reference for the systematics between different magma types. – haresfur Feb 16 '15 at 22:28
