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.

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
