metasomatism การใช้

• Hydrogen-ion metasomatism is the process that causes phyllic alteration.
• Effects of metasomatism in mantle peridotite can be either modal or cryptic.
• Metasomatism does further affect rocks derived from magma chamber walls.
• In this case the metamorphism grades into metasomatism.
• In modal metasomatism, new minerals are formed.
• The magmas of Ashikule probably did not form under the influence of water metasomatism.
• Partial melting of metasomatism-influenced mantle may be the origin of Longgang magmas.
• Potassium metasomatism was followed by sodium metasomatism.
• Potassium metasomatism was followed by sodium metasomatism.
• Metasomatism has also been considered critical for enriching source regions of some silica-undersaturated magmas.
• It commonly accompanies metasomatism and is often a feature of wall rock alteration around ore bodies.
• The magmas of the field probably formed in the lithosphere that had been affected by metasomatism.
• Changes in composition can be caused by processes such as weathering or metasomatism ( hydrothermal alteration ).
• It also occurs as alteration of manganese minerals such as rhodocrosite during low oxygen metamorphism and metasomatism.
• Because metamorphism usually requires water in order to facilitate metamorphic reactions, metasomatism and metamorphism nearly always occur together.
• As opposed to metasomatism, which is a chemical change caused by metamorphism, recrystallization is a physical process.
• Sulfidic jasperoids are typical examples of silica-sulfide metasomatism of dolostones, and are found in Nevada and Iran.
• Fluids rich in these have strongly affected the country rock and locally the granites themselves in a process called metasomatism.
• Trace elements indicate that the parent body had a complex geologic history with partial melting, melt migration and metasomatism.
• Metasomatism is the drastic change in the bulk chemical composition of a rock that often occurs during the processes of metamorphism.
