Piotr Sosnowski / Wikimedia Commons. Rock salt is an evaporite composed mostly of the mineral halite. It is the source of table salt as well as sylvite. Halite deposits are relatively soft rocks that are easily deformed. Under pressure, these deposits flow upwards to form large salt domes that distort the surrounding beds, often forming traps for oil and natural gas.Clastic Sedimentary Rocks. How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles. How do you distinguish halite from calcite?
