Formation

Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.
