Halite | Common Minerals
Halite gets its name from 'hals', the Greek name for salt. It is difficult to overstate the past importance of salt in both human and domesticated animal consumption. Without salt, widespread animal domestication (and hence modern civilization) could not have arisen. The sodium from salt is necessary for cells to function, so people need ...
The Role of Calcite Dissolution and Halite Thermal Expansion …
This research focuses on the analysis of the influence of two secondary salt weathering processes on the durability of rocks exposed to marine environments: chemical dissolution of rock forming minerals and differential thermal expansion between halite and the hosting rock. These processes are scarcely treated in research compared to salt …

1.. IntroductionNumerous works have analysed the impact of active tectonics on the evolution of fluvial systems and the development of river terraces and valley fills (Burbank and Anderson, 2001).However, the literature on the effects of other types of natural and human-induced deformation on fluvial systems, like halokinesis (Lucha et al., 2003), volcanotectonics …
Chemical Weathering Processes on the Earth's Surface
Halite's solubility product is K sp = 37.6.. Clearly, halite is highly soluble; at 25 °C and a pressure of 100 kPa, its solubility is 6.15 mol kg −1 (~351 g L −1).Since no hydrogen ions (H +) are involved, the process is independent of pH.Due to a number of factors, like the remarkable abundance in seawater of the two ions involved, several authors have probed into …
Fluid Inclusions in Surface‐temperature Halite: Sample …
We tested two common cooling methods, using heating/freezing stage and freezer, for studying fluid inclusions in halite precipitated in laboratory at conrtolled temperature of 25°C. While using the heating/freezing stage, halite samples were kept at –18°C for 40–50 min; whereas for freezer, samples were stored at –18°C for 1, 10, 20 ...
Red sea evaporites: Formation, creep and dissolution
The dissolution of submerged salt produces dense brines (McManus and Hanor, 1988; Esch, 1995) that fill seafloor depressions, such as in the Gulf of Mexico, Mediterranean Sea and Red Sea (Swallow and Creease, 1965; Shokes et al., 1977; Jongsma et al., 1983; Ranganathan, 1991; Rodriguez et al., 2017).However, these hypersaline pools are a negligible …

Strain-induced preferential dissolution of halite
CONCLUSIONS (1) Halite single crystals loaded dry and then placed in brine are preferen- tially dissolved at surfaces adjacent to regions of high plastic strain. Faster dissolution of crystalline material with high defect (dislocation line) concen- trations is the mechanism suggested to be responsible for this phenomenon.
Halite Mineral | Uses and Properties
Halite: Halite from Retsof, New York. Specimen is approximately 3 inches (7.6 centimeters) across. What is Halite? Halite is the mineral name for the substance that everyone knows as "salt." Its chemical name is sodium chloride, and a rock …

The dissolution rate of halite was determined by Wagner [1949] from the weight loss of thin plates of halite rock suspended in water to be 5.3 10 2 25% mol/m2 s. Alkattan et al. [1997] examined dissolution rate as a function of temperature, halite saturation degree, disk rotation speed, and concentrations of aqueous trace metals, and was found ...
Halite Mineral | Properties, Formation, Uses and Deposits
Halite, also known as rock salt or sodium chloride (NaCl), is a naturally occurring mineral that holds significant importance in various aspects of human life. This crystalline mineral is composed of equal parts sodium and chlorine ions and is renowned for its distinctive cubic crystal structure. Halite is not only a common mineral found in geological formations but also a …

1.. IntroductionPressure solution or dissolution precipitation creep (DPC) is a widespread deformation mechanism in the upper and intermediate levels of the crust, as shown by the microstructures developed from diagenesis through low-grade metamorphism (e.g. Elliot, 1973; Rutter, 1983; Gratier and Gamond, 1990).Dissolution of minerals proceeds along …
The rate of dissolution of halite in diluted Dead Sea brines
Dissolution of halite slices was performed in diluted Dead Sea (DS) brines, with and without stirring. The range of DS dilutions used in the experiments was wide, from 10% to 90%, and the ratios between solution volume to surface area of the halite slices varied from 6.7 to 27 ml solution per cm 2 halite. In the experiments with stirring, data interpretation was performed by …

A Plea for More Skepticism Toward Fluid Inclusions: Part II
Quartz-hosted brine inclusions that homogenize via halite dissolution occur in many magmatic-hydrothermal systems. In many cases their calculated minimum entrapment pressures are geologically unrealistically high, which has been interpreted to reflect accidental entrapment of halite crystals, and hence, to indicate halite saturation.
