5 Formation

5.1 Formation

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

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
