Abstarct: One of the most important evaporite deposits is the playa environment, which accounts for more than 80% of the world's evaporite deposits. Haji Ali Ghali Playa is located in the northernmost part of the Central Structural-Sedimentary Zone of Central Iran and in the middle of the eastern Alborz Mountains to the north of the Taroud-Chah Shirin volcanic-sedimentary strip. The most important geological units surrounding this playa are in the northern part of sedimentary rock units such as limestone, dolomite, shale and sandstone and in the southern part of the igneous rocks including basalt, andesite-basalt, andesite, trachy andesite, trachyite and pyroclastic rocks include tuff and agglomerate. In addition, intrusive bodies such as granodiorite, dacite, basaltic masses and playa units such as gypsum marls are in the eastern part of the region. During field visits, 68 samples were taken, of which 25 samples were analyzed for principal elements using ICP-MS and titration, and 43 samples were analyzed for sub-elements. The major elements of Haji Ali Ghali playa are baxsed on abundance of chlorine, sodium, sulfate, calcium, magnesium, potassium and lithium and minor elements include strontium, barium and rubidium. Studies show that the highest abundance of Cl anion is in the eastern part of the region and the highest amount of potassium in the western part of the region. baxsed on the results of the analysis, it was found that all major elements except magnesium and sodium have a positive correlation with each other. Mineralogical studies of the studied samples were performed using petrography and X-ray diffraction (XRD) methods. According to the measured grade, the elements under study are currently not economical or economically feasible.
