Formation
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.
