Sea Floor Metamorphism. This converts the olivine and pyroxene in basalt into hydrated silicates such as serpentine chlorite and talc. Up to 10 cash back Ocean-floor metamorphism is a concept that has arisen from recent studies of present oceanic ridges and fracture zones where new crust is being generated altered and deformed.
Produced by rapid applications of extreme pressure like meteorites asteroids. The metamorphic rocks exhibit considerable metasomatic alteration notably loss of Ca and Si and gain of Mg and Na in most cases. Metamorphism of Sea Floor The Earth is divided into tectonic plates.
Modern evidence is provided to support this hypothesis and to suggest that heavy metal rich solutions discharged from such systems are responsible for the formation of a metal enriched sedimentary component.
A unified model of sub-sea-floor metamorphism and mass transfer is proposed and possible differences between sub-sea-floor and terrestial geothermal systems are discussed. These changes can be correlated with exchange between basalt and hot seawater. Up to 10 cash back Ocean-floor metamorphism is a concept that has arisen from recent studies of present oceanic ridges and fracture zones where new crust is being generated altered and deformed. The zone of metamorphism that surrounds the intrusion is called the halo or aureole and rarely extends more than 100 meters into the country rock.
