1 Formation
1.1 Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
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.
