Spain is one of the main gypsum producers in the world. Spanish gypsum reserves are large
and a good knowledge of the location of the ore reserves permits to establish better
exploitation strategies. Plotting the Spanish major gypsum outcrops, using a GIS base, helps
to classify them by age, establish the main depositional character and determine the factors
controlling their origin. Evaporitic deposits from Cambrian to Quaternary are preserved
throughout Spain. The evaporites are formed by chemical precipitation of natural brines …

… The oldest evaporite vestiges in the Spanish geological record have been described in
carbonate materials, as gypsum and anhydrite pseudomorphs, in Cambrian deposits of the
Cantabro–Iberian basin (northern Spain). The first properly identified evaporite formation in …
A study of the spatial distribution and age of the gypsum-bearing units in Spain suggests a
wide variation in factors controlling the origin of gypsum deposits. The Spanish evaporite
precipitation from Permian to Jurassic times was controlled by global conditions such as …
