From an aqueous solution calcium sulphate is deposited as crystals of gypsum, but when the solution contains an excess of sodium or potassium chloride anhydrite is deposited.
Anhydrite is most frequently found in salt deposits with gypsum; it was, for instance, first discovered, in 1794, in a salt mine near Hall in Tirol.
Defn: A scaly granular variety of anhydrite of a grayish white color, used for ornamental purposes.
Defn: A variety of anhydrite composed of contorted plates fancied to resemble pieces of tripe.
The anhydrite found in gypsum deposits is formed both by direct precipitation from salt water and by subsequent alteration of the gypsum.
The hydration ofanhydrite to form gypsum, on the other hand, involves an increase of volume and may result in the doming up and shattering of the overlying sediments.
A variety of anhydrite composed of contorted plates fancied to resemble pieces of tripe.
A scaly granular variety of anhydrite of a grayish white color, used for ornamental purposes.
Paradox Member Salt, gypsum, and anhydrite with interbedded black and brown shale; some limestone.
As hydration occurred and the anhydrite was converted to gypsum, the gypsum expanded, thereby exerting both lateral and vertical pressure on the beds around it.
These observations appear to show that the change to anhydrite is a very gradual process at temperatures below a red heat.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "anhydrite" in a variety of sentences. We hope that you will now be able to make sentences using this word.
