Formation

Formation
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.   
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
