Concluding Remarks

In this module, we illustrated that density and viscosity can play a major role in the processes that take place within a magma chamber. Whether two or more unlike magmas mix by blending or mingling depends on the density and viscosity contrast that exists between them.

The experiment was shown to simulate the processes that might occur within a single stratified chamber. It clearly shows how both magmas could be simultaneously tapped in a single eruption and offers plausible explanation for the formation of "mixed" rocks.
