Rock salt was discovered in central Kansas in 1887 by speculation companies organized to drill for coal, gas, oil, or any valuable minerals they might encounter. ... Geology. Salt is called an evaporite mineral because it is formed by the evaporation of water. Gypsum and anhydrite are also evaporites. Sea water contains salt in solution.

Geomechanical simulation of energy storage in salt formations
In a homogeneous geological domain with rock salt, the location of that node is observed to be on the cavern's wall. This is because the cavern wall would undergo maximum stress in given time duration. From the results, it can be seen that as the creep forces increase over time, the strain rate becomes steeper, causing the magnitude of the ...

Rock Salt Type, Composition, Formation, Occurrence, Mining
Rock salt is mainly halite, a mineral made from sodium chloride, NaCl. Rock salt also contains trace amounts of clastic sedimentary particles like clay minerals. The clay minerals are usually crystals of secondary minerals like sylvite or hydrocarbons. Evaporative minerals like gypsum, anhydrite, or sylvite are also commonly found in rock salt.

Rock Salt
One finds rock salt deposits ringing dry lake beds, inland marginal seas, and enclosed bays and estuaries in arid regions of the world. At various times in the geologic past, very large bodies of water (such as the Mediterranean Sea and an old ocean that sat where the Atlantic Ocean sits now) also evaporated and made enormous deposits of rock salt.
