Frontiers | Damage Assessment of a Salt Dome in Jizan ...

The salt dome in Jizan, southwestern Saudi Arabia, has caused several problems related to underground dissolution, particularly in the old part of the city. Examples of these problems include surface collapse, building failure, fracturing, tilting, and road cracking. Analysis of the salt dome using X-ray diffraction (XRD) revealed the dominance of gypsum, anhydrite, and halite.

Part of the water of the Konarsiah salt diapir is discharged from eight brine springs, and a small part of it flows into an adjacent karst aquifer, emerging as the saline Konarsiah spring. The objectives of this study are to determine the changes of salt diapir dissolution and salinity of the water resources under the climate change.

Salt deformation - Wikipedia

Salt deformation is the change of shape of natural salt bodies in response to forces and mechanisms that controls salt flow. Such deformation can generate large salt structures such as underground salt layers, salt diapirs or salt sheets at the surface. Strictly speaking, salt structures are formed by rock salt that is composed of pure halite (NaCl) crystal.

In this way the structures called salt domes come to exist. When the dome gets closer to the surface, gypsum cap rocks are formed by increasingly intensive processes of dissolution followed by re-crystallization of halite and accompanying minerals caused by inflowing groundwater. The gypsum caps protect the salt domes from further weathering.

Halite is also formed from evaporation in salt springs, where saline water comes out of the ground in a salt reservoir and precipitates as rounded globular masses. In some underground salt deposits such as Texas and Louisiana, the salt is pushed up by an underground force through soft soil and forms arched structures known as a salt dome.

What is a Salt Dome? How do they form? - Geology

Salt domes serve as oil and natural gas reservoirs, sources of sulfur, sources of salt, underground storage sites for oil and natural gas, and disposal sites for hazardous waste. Oil and Natural Gas Reservoirs. Salt domes are very important to the petroleum industry. As a salt dome grows, the cap rock above it is arched upwards.

AN OVERVIEW OF THE

Caverns are created in the bedded salt deposits by dissolving the salt with fresh water or unsaturated brine. The process is begun by drilling a hole from the surface down into the salt-bearing formation. This may require a ore b hole in excess of 1,000 feet deep. As the well is drilled, several strings of steel casing are set into the well.

In the Orca basin, salt domes on the sea bottom expose the salt to the sea water. Where the salt dome interacts with the sea water, solution of the dome can occur as salt dissolves in water. The extreme salinity of the area immediately surrounding the salt dome, however, will create a pool of salt water that is denser than the surrounding sea.

The Zechstein (Upper Permian) salts are extensively distributed in the Northeast German Basin (NEGB). Their formation and movements have attracted great attention to discovering the accumulation and exploration of hydrocarbon sources, as well as the salt production. But the previous studies are validated in cases and a general view on these studies is scarce.

Introduction (Chapter 1) - Salt Tectonics

The world produced about 260 million tons of salt in 2008, extracted as brine or rock. Brine is extracted from formation water. Where rainfall is low and evaporation rates are high, sea water or saline lake water evaporates in successive solar evaporation ponds until salt crystallizes on the pond floor to a thickness of 10 to 25 cm.

Halite salt: The mineral Halite information and pictures

Halite, the natural form of salt, is a very common and well-known mineral. It is found in solid masses, and as a dissolved solution in the oceans and in salt lakes. The inland lakes that are rich in salt exist in arid regions, and may also be below sea level without an outlet. These lakes evaporate during dry seasons, causing a recession in the water level and an increase of salinity content.

Salt domes - SlideShare

Rock salt (the mineral halite) has two properties that enable it to form salt domes: 1) when salt is buried to depths greater than a few thousand feet, it will have a density that is much lower than most other sedimentary rocks; and, 2) salt has the ability to deform and flow like a high-viscosity fluid when it is under pressure.
