Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism
Origin
Southern Alps, France
Unknown
Discoverer
Dolomieu
Unknown
Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock
From minerals such as chlorite, serpentine, and epidote, and platy minerals such as muscovite and platy serpentine which are green in color

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
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.
