Magnesium is almost exclusively excreted in the urine, with 90% of the dose excreted during the first 24 hours after an intravenous infusion of MgSO4. The pharmacokinetic profile of MgSO4 after intravenous administration can be described by a 2-compartment model with a rapid distribution (a) phase, followed by a relative slow beta phase of elimination.

In oxidized melts, the presence of magmatic anhydrite would provide some evidence of this, but its preservation potential in the rock record is low, owing to the high solubility of sulfate in low-temperature aqueous fluids. In this study we have examined granitic and porphyry samples from porphyry copper ore deposits using quantitative ...
Next is calcium sulfate either as gypsum (CaSO 4 · 2H 2 O) or anhydrite (CaSO 4). The next most abundant evaporite mineral is halite (NaCl), commonly known as rock salt. These two minerals, gypsum/anhydrite and halite, constitute more than 95 % by volume of the world's Phanerozoic evaporates (Warren, 2010). Under conditions of extreme ...

Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates.In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant.One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum.It has many uses in industry. All forms are white solids that are poorly soluble in …
into gypsum proceeds until all the anhydrite present in the rock is converted to gypsum. This process (gypsication of anhydrite) is accompanied by about 61% increase in volume (Butscher et al. 2011, 2017; Jarzyna et al. 2021). Since clay-sulfate rock swelling includes groundwater ow, mechanical swelling and chemical reaction, as well as
