5 Formation
5.1 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.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
