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.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
