WebSep 27, 2024 · How does granite become gneiss? Gneiss is a rock of metamorphic origin, resulting from the deformation of arc sediments or granites. Its composition is made up of several minerals, more than 20% of potassium feldspar, plagioclase, and also quartz and biotite, which is why it is considered essentially quartzofeldspathic. WebSome kinds of metamorphic rocks -- granite gneiss and biotite schist are two examples -- are strongly banded or foliated. (Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.) Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned. incitement in south african law
