Review:

The Fuente de Piedra lagoon is a wetland with a high ecological value, it was one of the three first wetland included in the Ramsar convention and was declared Natural Reserve in 1989. The lagoon (13 km2) belongs to a closed basin (150 km2), where Miocene calcarenites outcrops, that host a freshwater aquifer, and the Chaotic Subbetic Complex (CSC), which defines the Miocene aquifer bottom. The CCS is a olistotrome made up of marly-gypsum matrix, and limestone, dolomite and marly blocks. The genetic model of the lagoon, the conceptual model of the hydrogeological system and the genetic-evolutive of the brine are closed related. The origin of the lagoon is related to karstification and collapse processes of the CCS gypsum-saline materials. The area presents high density contrast: shallow freshwater, the brackish water and the shallow and deep brines, whose salinity is an order of magnitude higher than seawater. Traditionally, based on classic models for closed basins in semiarid climates, the brine present in the system was considered of evaporative origin and it was only placed in the discharge zone. However, in the last decade, the IGME developed an intense research activity using geophysical, hydrochemistry, isotopes, natural tracers and numerical techniques. This has enabled to identify a genetic-evolutive model of basin brines and to propose a conceptual model of the hydrogeological system innovative, consistent and coherent with each other. This publication presents the report of the research project and the more relevant resulting papers of the thereof.
