Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.
