Caminite A new magnesium hydroxide sulfate hydrate
·24UC rnay precipitate abundant caminite and anhydrite Formation of caminite can drastically lower the pH of downwelling seawater in such systems and rapid removal of sulfate into caminite and anhydrite may prevent the reduction of much seawater sulfate to sulfide within the hydrothermal system Incorporation of seawater sulfate into caminite
Experimental Data on Solubility of the Two Calcium Sulfates
·Calcium sulfate exists in three forms namely dihydrate or gypsum CaSO4·2H2O anhydrite CaSO4 and hemihydrate or bassanite CaSO4· depending on temperature pressure pH and formation conditions The formation of calcium sulfates occurs widely in nature and in many engineering settings Herein a dataset containing the
