Often appears intercalated limestones and shales and layers generally located under salt deposits, having been deposited as one of the first minerals crystallized by the evaporation of salt water can be recrystallized from veins, forming the satin spar. You can also do this in the form of lenticular masses or scattered clays and shales, often formed by alteration of anhydrite crystals in these circumstances usually shows folds due to increased volume. It is found in volcanic regions, especially if the limestones have been affected by the action of sulfur vapors.



Massive cast: massive ore different colors depending on the impurities, opaque, matte, sometimes granular.

Lenticular: Lenticular submanifold earlier in smaller crystals.

Fibrous or columnar: Adding fibrous gypsum crystals, which occurs filling fractures with waxy or madreporic silky shine and clear color.

Acicular: colorless, transparent, prismatic crystals, with intense vitreous luster relatively common in sulfide alteration zones (Cartagena-La Union).

MYTHOLOGYGypsum is the most common sulfate and there are extensive deposits in many parts of the world, one of the commercial activities of the Roman city of Segóbriga (Cuenca), involved in the mining of gypsum speculate (lapis specularis), which since Segóbriga was transported to the port of Carthagonova (Cartagena), to be marketed in the rest of the Empire, where it was used in windows and decoration. Most plasters Central Catalonia formed in the ocean, in the early stages of the evaporation of sea that covered large part of this area, a process that eventually resulted in rock salt and sylvite.

ZODIAC SIGN: Capricorn.

USES: For agricultural marinade, construction is used to cover walls, as plates, retarder cement ore plaster, in medicine for curing bandages and immobilize broken bones, the study of the isotopy of the gypsum deposited in the ocean helps determine the temperature and fluctuations in the level of ocean waters in antiquity. Meditation, collection, decor, jewelry.
