WebThe essential mineral ingredients of phyllites are microcrystalline quartz, fine-grained micas (sericite, muscovite), and chlorite. The quartz is usually in the form of elongated thin lenses or veins within the sheets, which contain mainly fine-grained mica and chlorite. WebQuartzite has some appeal over quartz because of its environmental benefits. Quartzite is totally natural without any man-made polymers or pigments. Comparatively, quartzite may also be more resistant to scratching and acids than quartz. Quartzite registers around an 8 on the Moh’s mineral hardness scale.
