Greenschist vs Basaltic Trachyandesite


Basaltic Trachyandesite vs Greenschist


Definition

Definition
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism   
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface   

History
