Well develo-ped gypsum palaeokarst and some modern gypsum karst is present in the Fengfeng Formation (Ordovician) gypsum of the Shanxi and Hehei Provinces.1 Research background. Salt-gypsum beds refer to rock beds mainly composed of salts or gypsum. In the petroleum drilling industry, formations predominantly consisting of sodium chloride or other water-soluble inorganic salts, such as potassium chloride, magnesium chloride, calcium chloride, and gypsum or mirabilite, are referred to as salt-gypsum formations.
A 1.803 g sample of gypsum, a hydrated salt of calcium sulfate, CaSO4 is heated at a temperature greater than 170 degree Celsius in a crucible until a constant mass is reached. The mass of anhydrous CaSO4 salt is 1.426g. Calculate the percent by mass of water in the hydrated calcium sulfate salt. (1.803-1.427)/1.803 x 100.
The first purpose for gypsum is when it is used on soils with excessive amounts of salt (Na+). Too much sodium in soil will damage good soil structure by displacing other elements needed by plants. Salt is probably most damaging on clay soils. Applying gypsum for lawns will dislodge the sodium which slowly restores the proper soil structure.

Michigan ranks first in the United States in the production of calcium chloride (salt) and in gypsum, fourth in cement and sand and gravel, and is a large producer of crushed stone for a variety of purposes. Gypsum is incorporated into the soil, followed by application of salt-free irrigation water. The amount of calcium to apply depends on the quantity of sodium in the soil. Road de-icing salt or calcium chloride (CaCl 2) is also an option to provide calcium to soil, but it is more expensive than gypsum.As seawater evaporates, gypsum is the first 'salt' to be precipitated, followed by anhydrite, halite, and finally sylvite. Usually found with other evaporite and carbonate minerals, such as anhydrite, calcite, dolomite, borax, and halite, in altered carbonate rocks, gypsum may also be found with sulfur and pyrite.In archaeology, the term alabaster is a category of objects and artefacts made from the varieties of two different minerals: (i) the fine-grained, massive type of gypsum, [1] and (ii) the fine-grained, banded type of …Caprock sealing ability is one of the key geological factors to ensure the stable and safe operation of the underground gas storage (UGS). Gypsum salt rock is the high-quality caprock for oil and gas reservoirs, however, the effect of cyclic stress on its sealing capacity is still unclear, which restricts the construction progress of this kind of UGS.

Liquid gypsum application can increase the water infiltration to greater depths under the emitters over time due to soil particle ... Makes soils easier to work and improves soil aeration for better plant growth. The free calcium from Gypsum will replace the sodium on the clay particle, allowing the sodium (salts) to be leached out of the soil. Use liberally with organic soil amendments at the time of planting; will not burn and is non-irritating.
Dissolved gypsum is a salt and will increase the water's solute concentration. Irrigation water with low levels of leachable salts either penetrate poorly into soil or causes soil particles to degrade clogging up soil pores. The problem can be corrected with surface-applied gypsum or gypsum application to the irrigation water.

The analytic hierarchy process (AHP), which has the advantage of turning several ... 2. Gypsum Helps Reclaim Sodic Soils. Gypsum is used in the reclamation of sodic soils (Aldrich and Schoonover 1951). Where the exchangeable sodium percentage (ESP) of sodic soils is too high, it must be decreased for soil improvement and better crop growth. The most economical way is to add gypsum which supplies calcium.Gypsum is a soft mineral often found in shallow lake beds, especially salt lakes.
