Lost World Caverns
Desert rose is the colloquial name given to rose-like formations of crystal clusters of gypsum or baryte which include abundant sand grains.The 'petals' are crystals flattened on the c crystallographic axis, fanning open in radiating flattened crystal clusters. The rosette crystal habit tends to occur when the crystals form in arid sandy conditions,such as the evaporation of a shallow salt basin. The crystals form a circular array of flat plates, giving the rock a shape similar to a rose blossom.They can appear either as a single rose-like bloom or as clusters of blooms, with most sizes ranging from pea sized to 4 inches (10 cm) in diameter. The desert rose may also be known by the names: sand rose, rose rock, selenite rose, gypsum rose and baryte (barite) rose.
