摘要

本文采用XRF、X射线衍射(XRD)和傅里叶变换红外(FTIR)分析方法，研究了从sebkha Oum El Khialate盐水中提取的三种盐的地球化学和矿物学变化。元素分析表明富含具有经济利益的主要元素，如钾。与标准相比，微量元素分析产生高浓度的有害元素，如Cd和Cr，对人类消费构成威胁。XRD和FTIR分析显示，沿蒸发路径的矿物学变化包括该sebkha特有的矿物，如水杨石(CaCO3)，五硫酸钾(K2S5O16)，芒硝(Na2SO4)，硫酸铍(BeSO4)，水镁石(Mg(OH)2)和芒硝(Na2SO4·10h2o)。回收盐的地球化学和矿物学证明sebkha Oum Khialete是一种可用于工业和农业的潜在矿石资源。

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

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 display a variable mineralogy along the evaporation path including minerals that are specific for this sebkha, such as vaterite (CaCO3), potassium pentasulphate (K2S5O16), thenardite (Na2SO4), beryllium sulfate (BeSO4), brucite (Mg(OH)2), and mirabilite (Na2SO4·10 H2O). The geochemistry and mineralogy of recuperated salts prove the relevance of the sebkha Oum Khialete as a potential ore resource to be used in industry and agriculture.

期刊介绍： Resource Geology is an international journal focusing on economic geology, geochemistry and environmental geology. Its purpose is to contribute to the promotion of earth sciences related to metallic and non-metallic mineral deposits mainly in Asia, Oceania and the Circum-Pacific region, although other parts of the world are also considered. Launched in 1998 by the Society for Resource Geology, the journal is published quarterly in English, making it more accessible to the international geological community. The journal publishes high quality papers of interest to those engaged in research and exploration of mineral deposits.
