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.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
