The paper presents the proceedings of the temperature mapping in the square of 6 km2
carrying out on
the Dachnoe field of the thermal-mineral waters.
The number of measurements is 1318, total length of
profiles is 32650 m. Three zones of increased temperatures having linear nature are marked out. They
are orientated in two directions with40° and 310°
azimuths Thermal waters outlet takes place along
fault zones. According to the results of geological
survey and temperature mapping exploratory rotary
drilling of some bore-holes with depth up to 600 m
was carried out. Along the middle part of the
Nadezhda stream three bore-holes took out high
yield carbonic acid chloride and hydro-carbonate
waters having temperatures in the28 – 44°C range
on the surface. The area is perspective for the balneological use.
