Web2 apr. 2024 · Phyllite (/ˈfɪlaɪt/ FIL-yte) is a type of foliated metamorphic rock created from slate that is further metamorphosed so that very fine grained white mica achieves a preferred orientation. It is primarily composed of quartz, sericite mica, and chlorite . WebThe phyllite forms from pelitic sediments (shale and mudstone) at a slightly higher degree of regional metamorphism from slate ( Table 7.1 ). It may also originate from finely grained tuffs and clayey tuffite.

WebQuartzite (from German Quarzit) forms when quartz sandstones are metamorphosed. The term quartzite also implies its high quartz content.
