Formation

Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

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