What is bulk rock salt and what is usage in petroleum
Bulk rock salt refers to the commonly present mineral in nature “halite”. The bulk rock salt is composing mainly of sodium chloride- the table salt we all know. The myth about the bulk rock salt is that it composed of potassium sulfate. Although the mineral halite may contain impurities such as calcium sulfate and sylvite, potassium sulfate is hardly to found as impurities. The basic fact is that halite or the rock salt is the natural form of sodium chloride (table salt).
The rock salt, halite, is typically white in color or colorless. However, one may find halite with different colors such as light blue, dark blue, purple, red, pink, or gray. The various colors that halite could have depends on many factors such as the presence of other materials, the inclusion of impurities, and the abnormal structural changes in the crystal formation. Halite is basically a salt crystal.
How do we get this salt in its natural status?
The formation of bulk rock salt in nature is the result of evaporation of salt lacks or lagoons. When lacks lose connection to the open sea, water in the lacks becomes subject to the effect of evaporation. Although evaporation is a slow process, the effect enhanced in closed salt water. Over a hundred years, water evaporates from the closed lacks leaving the dissolved salt behind. When water decreases, salt sediment at the edge of the lack in the form of crystals. When water evaporates completely, only heaps of salt remains. Because the salt crystals aggregate to form of rock with nearly similar hardness, it called rock salt.
Bulk rock salt found in all around dry lake beds forming a ring shape. Rock salt also deposits around inland marginal seas and enclosed bays. At the estuaries, one can find deposits of rock salt as well. These places usually related to geological changes that occurred in the past, leading to evaporation of water from closed saltwater areas leaving tons and tons of rock salt as sediment in the beds.

The bulk rock salt around the world
Extensive underground salt beds are present in different areas around the world. In the USA, for example, salt beds extend from the Appalachian basin of western New York through parts of Ontario and under the Michigan Basin. Massive deposits of halite found in the Khewra salt mine close to Islamabad, Pakistan.
The bulk rock salt presents as salt domes in western and eastern Europe and in Iran.
In Egypt, the bulk rock salt comes from Siwa and Qattara depression in the East of Nile Valley. The salted bed in these areas of Egypt are rich in pure sodium chloride mineral, Halite, that is mined and sold to USA and Europe for road deicing and water softening.
Moreover, the salt lakes of Siwa provides the Western community with the needs of deicing salt and salts for water softeners.

Nature provides us with solutions to our upcoming problems. The mined bulk rock salt prepared to be suitable for human consumption as table salt. Salt also used to prepare salted food such as meat and fish.
In the cold areas of the world, salt from bulk rock salt used to reduce the freezing point of water, thus, the roads will not covered with these heaps of snow at 0 degrees Celsius. Large trucks used to apply salt to roads to keep them open and usable.
In agriculture, salt used to prevent the growth of annual meadow grass in turf production. Weeds are also exposed to salt water as a natural procedure to get rid of unwanted plants, thus allowing other plants (wanted) to grow without interruption.
The bulk rock salt also used in domestic purposes. It used as a cleansing agent. Basically, coarse salt used to remove oil and grease and stain. It naturally obtained soap. The rock salt also used as a water softeners.
The sticky spills are dried out and hardened when soaked in salt. So, we can use them with ease.
The bulk rock salt is handcrafted to create a salt lamp. The light emitted from inside the handcrafted piece is very stunning. Moreover, the salt lamp has medical uses. The emitted ions help in asthma and allergies. The salt lamps are so crafted that you can hardly find two pieces similar to each other. It is a very awesome decorative idea as well.
it is very interesting to know that the bulk rock salt acts as “traps” for petroleum in the Earth crust. When the geologists discover a dome of salt the subsurface layer in the Earth crust, petroleum is more likely to lie behind salt heaps.
From the geological viewpoint, salt domes are vertical diapirs. Diapirs are masses of salt in a pipe-like form that comes up from the salt beds. The heavy weight of the overlying rock on the bulk rock salt pushes some salt masses upwards forming diapirs. These salt domes are composed of anhydrite, gypsum, and Sulphur along with halite and sylvite. One can find such salt domes along the Gulf coasts of Texas and Louisiana, USA. The importance of this geographic construction is the association with petroleum deposits. Apart from the USA, such salt domes are present in Germany, Spain, and the Netherland. They are also present in East Europe in Romania and in Iran.
