In this chapter, the significance of micromorphological features of soluble salt occurrences in soil environments is discussed. It is largely confined to evaporite minerals in soils of arid regions, exclusive of gypsum (see Poch et al., 2018).Sulphate minerals that formed in a context of sulphide oxidation are treated elsewhere (Mees & Stoops, 2018).

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.

thenardite overlies a massive halite and decimeter-thick beds of glauberite. Thus, unlike the broadly distributed glauberite, the deposit of thenardite is restricted to a relatively small area in the central part of the basin (Ordóñez et al., 1991). Above the thenardite layer, there is a layer of mirabilite (several cm
