5 Formation

5.1 Formation

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.

Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
