Geochemistry and mineralogy of the sebkha Oum El Khialate evaporites mixtures, southeastern Tunisia

Abstract: This work is meant to study the variation of geochemistry and mineralogy of three salts recuperated from brines of the sebkha Oum El Khialate based on XRF, X-ray diffraction (XRD), and Fourier transform infrared (FTIR) analyses.Elemental analyses indicate enrichment with major element having an economic interest such as potassium. Compared to standards, minor elements analyses yield high concentrations of hazardous elements such as Cd and Cr, and represent a threat for human consumption. XRD and FTIR analyses … Show more

“…However, adequate identification of minerals essentially requires the detection of at least two or more peaks that are detectable in an XRD pattern. Recent previous studies investigated the mineralogy [64,65] and geochemistry [66] of salt in other Tunisian sebkhas based on XRD and infrared spectroscopy respectively. The samples were subsequently X-rayed to identify the mineralogy of different evaporites precipitated after each stage of evaporation.…”
