Formation

Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

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.
