Salt is a sedimentary rock that behaves in ways that can make it both an extrusive rock and an intrusive rock. As pressure on beds of salt builds up it often creates pressure differentials that cause it to rise in what is known as a diapir, which is a body of salt rising slowly through other sediments, even consolidated shales and sandstones. In many cases it actually penetrats the surface and flattens out, becoming an ext
