The dependence of gypsum morphology on the chemical composition can therefore be a tool for interpreting the paleo-chemistry and environments of solutions from which gypsum in the geological record precipitated. In addition, the morphology of the gypsum that will precipitate in the Dead Sea once the Red Sea-Dead Sea conduit is built will determine if the crystals will remain in suspension in the surface brine, thereby leading to “whitening” of the lake. Despite its importance, little is known about the impact of the different parameters on the morphology of gypsum precipitated from natural brines. In the present study we conducted single point batch experiments with mixtures of Dead Sea - Red Sea brines and utilized image processing techniques to study the morphology of the gypsum that precipitated from different solution compositions at different degrees of oversaturation. The results from the first data set towards the understanding of what controls the morphology of gypsum while providing a preliminary tool for the forecast of the future of the Dead Sea are presented here.</p></div>","PeriodicalId":101039,"journal":{"name":"Procedia Earth and Planetary Science","volume":"17 ","pages":"Pages 376-379"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeps.2016.12.095","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76252496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tailings containing non extracted U and its radioactive progenies are currently stored under water in a basin extending over 18ha. To predict U (100-400 ppm) and <sup>226</sup>Ra (10-70Bq.g<sup>-1</sup>) mobility, a detailed chemical, mineralogical and radiological characterization of the phases is required. For this, tailings sampling was performed to collect undisturbed samples close of <em>in situ</em> conditions. Preliminary characterizations evidenced good correlation between facies (to link with the extraction mode), granulometry, U concentration and <sup>226</sup>Ra activity. U and <sup>226</sup>Ra are concentrated in the silty-clay facies mainly as inherited monazites and neoformation of uranyl phosphates known for their low solubility. Clay minerals and Fe-oxi-hydroxides are also encountered and may play an important role in radionuclide trapping by sorption processes. These preliminary results confirm the immobilization of U and <sup>226</sup>Ra within the tailings, even though, additional experiments are needed to determine the extent of U and <sup>226</sup>Ra sorbed on Fe-oxi-hydroxides and on clay minerals.</p></div>","PeriodicalId":101039,"journal":{"name":"Procedia Earth and Planetary Science","volume":"17 ","pages":"Pages 308-311"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeps.2016.12.067","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80963546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
