Archaeological Significance
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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
