Definition
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

Etymology
From minerals such as chlorite, serpentine, and epidote, and platy minerals such as muscovite and platy serpentine which are green in color

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

More about Greenschist and Marble
Here you can know more about Greenschist and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Greenschist and Marble 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 Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Greenschist vs Marble, 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Greenschist is Layered and Shiny and that of Marble is Veined and Shiny. Properties of rock is another aspect for Greenschist vs Marble. The hardness of Greenschist is 3.5-4 and that of Marble is 3-4. The types of Greenschist are Metamorphic rock whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Greenschist and Marble is white.
