Formation

Formation

Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Hornfels is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
