Formation

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

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.
