Abstract

A groundwater sampling has been carried out in Sierra de Gador (SE Spain) with the aim of determining the processes in which minor ions are involved. Previous works have allowed us to differentiate four groups according to the major ion content. This study enables to subdivide one of these groups. The SO42-/Ba2+ relationship shows two distinct trends, controlled by the precipitation of barite in the sulfated samples. Ions as lithium and boron are related to the existence of sulfate and to the groundwater thermalism. Last, the ion Br is a useful indicator of salinity in the samples.
