Desert rose, Gypsum, 866 g 19 x 9 cm

45.00 € 38.25 €

Réf: M2482

The desert rose is an evaporite. It is a gypsum aggregate. The way its constituent elements bond together is similar to the arrangement of a rose's petals.

Desert sand provides these building blocks (sand, gypsum, or hydrated calcium sulfate), and the desert rose—also known as a sand rose—forms through the evaporation of capillary water from the soil.
