Formation

Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.

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.
