Volcanic and Igneous Rock Types - Explore Volcanoes
This is where we find well known volcanic rocks such as Andesite and Dacite. A magma or melt as it cools in the magma chamber undergoes a process called fractional crystallisation. As the melt cools crystals form the more silica rich ones are less dense and float to the top the Fe/Mg minerals settle nearer the bottom .
