Relationships among the mineralogy, morphology and the formation processes of salt accumulations
were studied in three sampling areas in the Flumen-Monegros district, which represent three
geochemical environments [Na-SO4-CI, Na-(Mg)-SO4-C1 and Na-CO3-SO4-C1], according to
chemical and mineralogical results.
The samples included both natural ones and others that were obtained in the laboratory by the
crystallization of brines with and without substrate. A climatic chamber was used to reproduce the
environmental conditions.
Laboratory crystallization of brines without soil substrate does not always reproduce the natural
mineral associations. Such associations were reproduced, however, when the crystallization was
carried out with the epipedon. New morphologies are described for bloedite (radiating prismatic, and
foliated rosette-like) and burkeite ( book plates and spheroidal association of plates), the latter formed
through capillary evaporation.
X-ray diffraction, scanning electron microscopy (SE and BSE modes), energy dispersive X-ray
spectrometry and polarized light microscopy were some of the techniques used, supplemented by
chemical data.
