Mineralogía de los sedimentos de la Laguna de Fuente de Piedra (provincia de Málaga)

Abstract

Sampling of sediments from the Fuente de Piedra playa lake (Málaga province, Spain) has been carried out both in the surface salt crust and in two shallow holes. The following minerals have been mainly indentified: quartz, feldspars, phyllosilicates, calcite, dolomite, gypsum, halite and hexahydrite. There seems to exist a lateral zonation with increasing salt contents towards the center ofthe Lake, as well as a vertical trend that is characterized for two processes: the carbonates dolomitization and the diagenetic growing of gypsum cristals
