In addition, if a felsic rock is found to be metamorphic with no traces of volcanic protolith (i.e. While the former is created in high-temperature lava that leads to extremely low viscosity, the latter has a high viscosity. This is why silica content has been chosen to classify igneous rocks with higher silica content making a rock Felsic while lower silica content making them Mafic. Felsic, intermediate and mafic igneous rocks differ in their mineral composition.
