Presented are the geological-geographical structural characteristics of the northeastern part of the Barguzin depression with a detailed description of the thermal springs (Kuchigerskii, Ukhmeiskii and Seyuiskii) and geological and hydrogeological condi tions of their discharge. Aerial photographs were used to identify a network of disjunctive dislocations represented by the general (Barguzinskii) fault and by the local (Ulyugninskii, Khakharkhai-Barguzinskii, Dzherginskii and Seyuiskii) faults. It is shown that the outcrops of thermal springs are connected with the intersection nodes of faults of several directions. New data on macro- and micro-component composition of the water, therapeutic mud and free gases are presented. It is determined that the content of La, Mn, Pb, Rb, Co, Cd, Ni, Zn, Cr and Sr in the water of the springs is above the concentrations of these chemical elements in Lake Baikal. High contents of Sr, Rb, Zr and Ba was observed in the mud composition of the Kuchigerskii and Umkheiskii thermal springs. It is established that the Kuchigerskii source is dominated by methane of organic origin and by nitrogen, while nitrogen is dominant in the Umkheiskii spring. The current status of the utilization of the thermal springs for medical and rec reational purposes is outlined. A high balneological potential of the thermal springs in the northern part of the Barguzin depres sion is shown.
