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.

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
