Definition of Protoliths. Meaning of Protoliths. Synonyms of Protoliths

- variety of protoliths. Identifying a protolith is a major aim of metamorphic geology. Protoliths are non-metamorphic rocks and have no protoliths themselves...
- Skarns may form by metamorphic recrystallization of impure carbonate protoliths, bimetasomatic reaction of different lithologies, and infiltration metasomatism...
- Primary sedimentary textures and structures of the original carbonate rock (protolith) have typically been modified or destro****. Pure white marble is the result...
- chlorite, from Maurienne Valley in the French Alps Composition Quartz Physical Characteristics Fabric Non-foliated Relationships Protoliths Quartz Sandstone...
- metamorphism creates minerals entirely based upon the chemistry of the protolith, certain 'dirty marls' and volcanic sediments may also metamorphose to...
- new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F)...
- type of the original rock (the protolith) is discernible, the schist is usually given a name reflecting its protolith, such as schistose metasandstone...
- certain highly deformed gneisses produced by metamorphism of sedimentary protoliths. The moderate temperatures may reflect the presence of greater amounts...
