1 Formation
1.1 Formation
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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
