5 Formation

5.1 Formation

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.

Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
