Bandar Abbas, Hormozgan province has an area with numerous hot springs.The Springsis located in FoldedZagros geological zone, and the host rocks of the springs are Cretaceous to Miocene limestones. Water samples from four hot springs and one cold spring were collected in two times, April (wet condition) and September (dry condition) 2013, In order to evaluate their environmental geochemistry. Temperature, pH, Eh and electrical conductivity (EC) were measured on site. Major and trace elements were analyzed by ICP-OES method. Also, elements such as Hg, As, Bi and Sb were measured by using atomic fluorescence method at detection limit of ppb. Trace elements are relatively high from environmental standards. Concentrations of U, Th and REE in springs water is high. Hydro geochemical studies indicate that high concentration of chloride in the water springs. The hydro chemical facies of hot and cold springs are NaCl and H2S gas boiling type. Genesis of the thermal springs indicate that these springs was derived from an ancient hydrothermal\source and high concentrations of chloride, indicating the high depth of the source.
