Desert Rose

Desert Rose
is the name given to rosette formations of
the minerals gypsum and barite with sand
inclusions. The 'petals' are crystals
flattened , fanning open along
characteristic gypsum cleavage
planes. The rosette crystal habit tends to
occur when the crystals form in arid sandy
conditions, such as
the evaporation of a shallow salt
basin.Desert roses are mineral formations
that are found on the surface and are
beautiful examples of the
natural power of the shaping forces of
wind, water and pressure in dry, arid
regions.Desert roses are only found in
deserts, which is how they got the name.
