Saline minerals (soluble evaporites) | SpringerLink
Mirabilite (Na 2 SO 4 ·10H 2 O) forms short prismatic crystals sometimes elongated parallel to the b axis, or is occasionally thin and tabular. Mirabilite is the typical mineral deposited by seawater, brines, or alkali-sulfate lakes during the winter season because of the strong negative-temperature coefficient of mirabilite solubility.

Mirabilite Spring Mounds Near Great Salt Lake Marina
In late October 2019, as air temperatures started to cool to near freezing, unique mineral mounds began forming on the south shore of Great Salt Lake, just east of the Great Salt Lake Marina. They are not composed of common table salt (sodium chloride—NaCl), but mirabilite (hydrated sodium sulfate—Na2SO4•10H2O), also known as Glauber's ...

In mirabilite, much of the interlayer hydrogen bonding is aligned with the a-axis; it is therefore slightly surprising to find that the direction of maximum thermal expansion is inclined by more than 30° to this direction. It is possibly of relevance that the hydrogen bonds donated by the two interstitial water molecules O10 and O11 are more ...

Rare Occurrence of Mirabilite in the Thirteenth-Century
Mirabilite, also known as Glauber's salt, is a hydrous salt of sodium sulphate (Na 2 SO 4 ·10H 2 O). This is a relatively rare mineral that forms under certain conditions through the evaporation of brines rich in Na and SO 4.It is found in the sodium sulphate deposits in the Northern Great Plains of Canada, on the surface of playa lakes in Central and Northeast …

The research by Ke and Wang demonstrates that external application of mirabilite can diminish inflammation, relieve pain, and prevent infections. In some clinical reports, mirabilite is used to treat phlebitis of various causes (9–11). However, the majority of these reports are clinical observations, which lack support of the experimental data.

Mirabilite is a common TCM which mainly contains sodium sulfate (Na 2 SO 4 ·10H 2 O). It can absorb osmotic solution and eliminate edema. The external application of mirabilite can help patients form a hyperosmotic state locally, and promote the local internal water to be absorbed outside through osmotic pressure.

Mirabilite has a Raman spectrum very similar to the free sulphate anion in solution, which is probably due to the mobility of oxygen atoms within the sulphate tetrahedron. The oxygen atoms in the heptahydrate sulphate groups have no partial occupancy, and predicted peak splitting is observed in the region 400–1200 cm −1 .
