Definition
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
Origin
Unknown
European Foreland Basins

Arnold H. Bouma
Etymology
From minerals such as chlorite, serpentine, and epidote, and platy minerals such as muscovite and platy serpentine which are green in color
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Formation
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

More about Greenschist and Turbidite
Here you can know more about Greenschist and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Greenschist and Turbidite consists of mineral content and compound content. The mineral content of Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Greenschist vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Greenschist is available in dark greenish - grey, green colors whereas, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Greenschist is Layered and Shiny and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Greenschist vs Turbidite. The hardness of Greenschist is 3.5-4 and that of Turbidite is 3. The types of Greenschist are Not Available whereas types of Turbidite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Greenschist is white while that of Turbidite is white, greenish white or grey.
