| 11. | It commonly accompanies metasomatism and is often a feature of wall rock alteration around ore bodies.
|
| 12. | The magmas of the field probably formed in the lithosphere that had been affected by metasomatism.
|
| 13. | Changes in composition can be caused by processes such as weathering or metasomatism ( hydrothermal alteration ).
|
| 14. | It also occurs as alteration of manganese minerals such as rhodocrosite during low oxygen metamorphism and metasomatism.
|
| 15. | Because metamorphism usually requires water in order to facilitate metamorphic reactions, metasomatism and metamorphism nearly always occur together.
|
| 16. | As opposed to metasomatism, which is a chemical change caused by metamorphism, recrystallization is a physical process.
|
| 17. | Sulfidic jasperoids are typical examples of silica-sulfide metasomatism of dolostones, and are found in Nevada and Iran.
|
| 18. | Fluids rich in these have strongly affected the country rock and locally the granites themselves in a process called metasomatism.
|
| 19. | Trace elements indicate that the parent body had a complex geologic history with partial melting, melt migration and metasomatism.
|
| 20. | Metasomatism is the drastic change in the bulk chemical composition of a rock that often occurs during the processes of metamorphism.
