Formation
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
  
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.
