About 37 million years ago, Central Catalonia was occupied by an open ocean arm in the Atlantic, but that elongated golf was coming to an end, as continental movements and other reasons caused its communication to be closed with the oceans. That sealed ocean, under a hot and dry climate, evaporated without rains compensating for lost water; the sea was reduced while the concentration of salts rose, which began to precipitate, depositing first the plaster, then the common salt and potassium salt. What had been the sea became a salt plain, but for a short time, since the rivers and streams that descended from the mountains were depositing sediments above the salt, which was buried. The materials that were sedimented in that closed basin dried and oxidized by contact with the air, taking reddish colors. They are called "continental" because they have not been deposited in the sea, which is the most common. We summarize here the great changes in the map of the north of the Iberian Peninsula.

GEOPOLIC GEOLOGICAL OUTDOORS WITH JOSEP M. MATA
Millions of years ago, in the geographical heart of Catalonia, there was a sea that disappeared pushed by the rise of mountain ranges like the Pyrenees. The geological processes have left a territory with spectacular rock formations such as Montserrat and rich natural resources such as salt, plaster or lime. Discover our Geopark with the geological exits of Professor Josep M. Mata.
