List of products by manufacturer Sal de Añana

Añana salt , salt spring water with more than 200 million years of training.
During the Triassic period it began about 251 million years ago and ended about 200 million years ago, at a time when all continents were united to form the continent called Pangea, Salinas de Anana he was submerged under a great ocean. Evaporation of the water caused the deposition of large evaporite layers on its bottom that, over time, were covered by other layers.

The existence of salt in Añana is explained by the geological phenomenon called diapir. Generally it involves the ascent to the land area of ​​older materials due to its lower density, just as a bubble of air immersed in a liquid has an upward motion.

This particular process began about 220 million when the evaporite rocks of Triassic Keuper facies -situadas about 5 kilometers deep began to rise to the surface, dragging materials that characterize the salt landscape: carniolas, ofitas, limestones. marl, clays, etc. This process is still active.

The water drop on the diapiro rain through, first, the upper strata of rock and then the salt layers, surfacing again to the surface as springs or seeps hypersaline. Anana springs provide an average flow of about 2 liters per second, with a salt concentration around 210 grams per liter.

The hydrological system related to the diapiro is completed by the Lake Arreo, whose waters due to its location in a closed basin above evaporites, are also saline character. Both the lake and the salt deposits contain important paleoenvironmental and paleoclimatic information as well as a typical biodiversity of saline environments. For this reason and in order to preserve them, both spaces have been included in the Ramsar List of Wetlands of international importance.
