Definition

Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic

Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

History

Origin

Discoverer

Unknown

Etymology

From the Greek meaning sounding stone because of the metallic sound it produces if an unfractured plate is hit

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

Formation

Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

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.

Phonolite vs Greenschist Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Phonolite and Greenschist Reserves. Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic. Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Phonolite vs Greenschist information and Phonolite vs Greenschist characteristics in the upcoming sections.
