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 …

mirabilite (e.g. Palache et al. 1951). The eutectic between mirabilite and ice Ih is at 271.85 K, 4.15 wt.% Na 2SO 4, and the solubility increases rapidly with temperature up to the peritectic at 305.534 K, 33.2 wt.% Na 2SO 4 where mi-rabilite undergoes incongruent melting to anhydrous sodium sulfate (orthorhombic phase V, Fddd, thenardite).

Mirabilite-precipitating springs and the formation of terraced mounds have been documented in the Canadian Arctic, central Spain, and the Antarctic. These features are ephemeral; warmer spring temperatures will eventually turn the mirabilite to the powdery, easily eroded thenardite, if the rising lake level doesn't erode the mounds first. ...

Mirabilite, also known as Glauber's salt, is a hydrous sodium sulfate mineral with the chemical formula Na2SO4·10H2O. It is a vitreous, colorless to white monoclinic mineral that forms as an evaporite from sodium sulfate-bearing brines. It is found around saline springs and along saline playa lakes. Associated minerals include gypsum, halite, thenardite, …

The mirabilite signal is converted into thenardite in 74 h. After 36 h already 80% of the mirabilite is converted. The two dashed lines plotted in the graph are the peaks which are used for Fig. 6 b. Here, the signal of mirabilite is plotted versus thenardite. It seems that the thenardite and mirabilite signals are one-to-one interchangeable.

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 .

It is similar to Mirabilite, a chemically similar mineral to Thenardite that, unlike Thenardite, contains water in its structure. Mirabilite is an unstable mineral, and will dehydrate and lose its water when exposed to air, thereby changing to Thenardite. These altered specimens are in fact Thenardite pseudomorphs after Mirabilite.
