Greenschist vs Syenite


Definition

Definition
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals   
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

Formation

Formation
Syenites 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.

Syenite 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 Syenite and Greenschist Reserves. Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals. 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 Syenite vs Greenschist information and Syenite vs Greenschist characteristics in the upcoming sections.
