Magnesium sulfate Uses, Side Effects & Warnings
Magnesium sulfate taken orally should produce a bowel movement within 30 minutes to 6 hours. Drink plenty of liquids while you are taking magnesium sulfate. If you have rectal bleeding or if you do not have a bowel movement after using magnesium sulfate as a laxative, stop using the medication and call your doctor at once. ...

Amending Soils with Lime or Gypsum (NRCS 333) | AgBMPs
Gypsum is a calcium sulfate containing product that provides both calcium and sulfate to the soil system. No change in pH can be expected from a gypsum application. The calcium in gypsum can replace sodium in sodic soils or aluminum where aluminum toxicity might be a concern. Neither of these situations are common in Ohio.

Presence of sulfate does not inhibit low-temperature dolomite …
It is revealed that a variation of sulfate concentration in solution does not affect the formation of dolomite mediated by halophilic archaea, but an increase of salinity enhances this process, and under natural conditions, an increase in salinity may be more significant than the decrease of sulfates in microbe-mediated dolmite formation.

The Dolomite Problem: A Matter of Time
Dolomite, CaMg(CO 3) 2, is an abundant carbonate mineral in ancient rock formations, but it is extremely scarce in modern sedimentary environments.This intriguing observation has been repeatedly referred to as the "dolomite problem" in the geological literature. Many geoscientists over time have almost obsessively searched for a solution …

Dolomite and Dolomitization | SpringerLink
The crystal structure of dolomite is similar to calcite with Mg ions substituting for Ca in every other layer. To accommodate this substitution, due to differences in bond lengths between Ca–CO 3 and Mg–CO 3 (238 pm versus 208 pm, respectively), CO 3 in the Mg layer is uniformly rotated about the threefold axis relative to calcite (Reeder and …
