Description :
In this paper, after a short geologic outline of the Naica area, the mechanisms responsible for the genesis and the evolutionary steps of the Naica cave are discussed in detail mainly on the basis of the chemical deposits hosted inside the cavities. The anthropogenic processes induced by the mine depression cone had relevant consequences on the cave development giving rise to the evolution of several new diagenetic minerals, but also greatly enhancing the condensation corrosion and dissolution processes which, in a few years, will be responsible not only for the damage of the giant gypsum crystals but also for their complete destruction. For this reason one of the main tasks for the scientists is to search for the best way to preserve this underground world.
