Let's trace its formation from its protoliths - the sedimentary rocks from which it forms. These are usually shales or mudstones. In the convergent plate boundary environment, heat and chemical activity transform the clay minerals of shales and mudstones into platy mica minerals such as muscovite, biotite, and chlorite. The directed pressure pushes the transforming clay minerals …
