Mirabilite
noun ·Rare ·Advanced level
Definitions
- 1 An evaporite, consisting of sodium sulfate, with the chemical formula Na₂SO₄·10H₂O.
"Mounds of mirabilite have been observed near the north-west side of White Island, (e.g., Debenham 1965). These mirabilites probably originated by infiltration of sea water into the ice shelf, followed by ablation of the surface until the brines were exposed to evaporation and freeze concentration with precipitation of mirabilite on the surface."

Etymology
From Latin mīrābilis (“miraculous”) + -ite. From the Latin term sal mirabilis (“wonderful salt”), which was used by German-Dutch alchemist Johann Rudolph Glauber (1604–1670) after he inadvertently synthesised the substance.
