| 11. | The field is composed of a numerous sand reservoirs bounded by Anhydrite and Salt section.
|
| 12. | For example, iron oxides are converted to iron hydroxides and the hydration of anhydrite forms gypsum.
|
| 13. | Salt domes contain anhydrite, gypsum, and native sulfur, in addition to halite and sylvite.
|
| 14. | Natural anhydrite does not react with water, even over geological timescales, unless very finely ground.
|
| 15. | Nonporous caprock such as halite ( rock salt ) or anhydrite is more effective in trapping helium.
|
| 16. | The front section of the terminal loop is located in depleted anhydrite, which is brittle in consistency.
|
| 17. | The Leofnard Member at the top consists of halite with minor interbeds of dolostone, anhydrite and mudstone.
|
| 18. | As for anhydrite, its solubility in saline solutions and in brines is also strongly dependent on NaCl concentration.
|
| 19. | In the form of ?-anhydrite ( the anhydrous form ), it is used as a desiccant.
|
| 20. | It occurs associated with halite, polyhalite, anhydrite, gypsum, thenardite, mirabilite, sassolite and blodite.
