Аннотация:The geological setting and chemical composition of the Garm Chashma, Firuza MGU, Tandykul, Obigarm, and Khojaobigarm thermal springs of the Pamir and foothills of Tien Shan are considered. Their first trace element (ICP MS) composition is provided. On the basis of the B: Cl and B: Br (as well as Li: Rb: Cs) ratios, the genesis of the springs was determined. The paleotemperature of the springs based on the Na-K geothermometer (136–240°C) indicate the deep formation conditions. The first δ18O and δD data are evidence of the most likely meteoric origin of the thermal springs.
