glauberite

Associated minerals include gypsum, halite, thenardite, trona, glauberite, and epsomite.

Sodium sulfate is also found as glauberite, a calcium sodium sulfate mineral.

Glauberite is a sodium calcium sulfate mineral with the formula NaCa(SO), which forms as an evaporite.

Common minerals that are found in these deposits include blödite, borax, epsomite, gaylussite, glauberite, mirabilite, thenardite and trona.

Because of its solubility, glauberite is often dissolved away from the crystal matrix leaving a mould into which other minerals are deposited giving them an anomalous crystal form.

Ulexite is frequently found associated with colemanite, borax, meyerhofferite, hydroboracite, probertite, glauberite, trona, mirabilite, calcite, gypsum and halite.
