Archaeological Significance
Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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.
