anhydrite การใช้

• The anhydrite and gypsum react with organic material to form calcite.
• Sulfur will be obtained from pyrites, then gypsum or anhydrite.
• The overlying Shell Lake Member consists primarily of anhydrite interbedded with dolostone.
• It is often accompanied by anhydrite, carnallite, halite, and kieserite.
• Other minerals include anhydrite, augite, and plagioclase.
• Complete dehydration of this mixture yields the optimum 2 % ?-anhydrite.
• When gypsum dehydrates severely, anhydrite is formed.
• The calcium sulfate, anhydrite, was present as phenocrysts in the erupted tephra.
• The halite ( salt ) is removed first, leaving behind gypsum and anhydrite.
• A geochemical process called anhydrite swelling has been confirmed as the cause of these uplifts.
• The field is composed of a numerous sand reservoirs bounded by Anhydrite and Salt section.
• For example, iron oxides are converted to iron hydroxides and the hydration of anhydrite forms gypsum.
• Salt domes contain anhydrite, gypsum, and native sulfur, in addition to halite and sylvite.
• Natural anhydrite does not react with water, even over geological timescales, unless very finely ground.
• Nonporous caprock such as halite ( rock salt ) or anhydrite is more effective in trapping helium.
• The front section of the terminal loop is located in depleted anhydrite, which is brittle in consistency.
• The Leofnard Member at the top consists of halite with minor interbeds of dolostone, anhydrite and mudstone.
• As for anhydrite, its solubility in saline solutions and in brines is also strongly dependent on NaCl concentration.
• In the form of ?-anhydrite ( the anhydrous form ), it is used as a desiccant.
• It occurs associated with halite, polyhalite, anhydrite, gypsum, thenardite, mirabilite, sassolite and blodite.
