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.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
