Lime Vs Gypsum | Should You Use Lime Or Gypsum?
Lime and gypsum both work to add calcium to your soil. Gypsum can also remove sodium and add sulfur to soil, but it can't balance pH levels like lime can. Both gypsum and lime can help improve various nutrient levels that can damage your , but it's important to understand your soil before deciding which is best for its health.

The onset of reflux results in a reversal in groundwater flow ...
KGS--Kansas Rocks and Minerals--Minerals
Kansas anhydrite is found in Permian-age deposits associated with beds of gypsum, dolomite, and red silt. With gypsum, it caps many of the Red Hills of Barber and other counties. Gypsum (hardness 2) Gypsum is calcium sulfate containing water (CaSO 4 · 2H 2 O). The same chemical compound without water is anhydrite, a quite different mineral.
Dolomitization, gypsum calcitization and silicification in …
Immediately following growth of gypsum, dolomite replaced the original calcite (or possibly aragonite) muds, the microbial community and the gypsum. Partial or total replacement of gypsum by dolomite was related mainly to the biomineralization of endolithic microbial communities on gypsum crystals. Later calcitization took place …

Gypsum | Common Minerals
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.
Dolomite
Dolomite is a carbonate mineral, consisting of calcium magnesium carbonate. It was first described as the 'stinking stone' by Belsazar Hacquet, an Austrian naturalist. Later, Déodat Gratet de Dolomieu, a French naturalist and geologist, described it as a rock from the Dolomite Alps in Italy. Properties of Dolomite
