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.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
