Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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.
