Noble gases may be considered as the most prominent tracers of natural fluids, including hydrocarbons. The atmosphere is the only source of 20Ne, 36Ar, 84Kr, 130Xe in subsurface environments, and their concentrations in pore waters after recharge are

Thermal springs with water temperatures up to 97 °C were sampled in the Chukotka Peninsula of the north-eastern Asia on the area of ~ 60,000 km2. He and Ar isotope ratios in bubbling gases were measured in 30 samples of from 23 spring groups. 3Не/

Terrestrial heat flow density, q, is inversely correlated with the age, t, of tectono-magmatic activity in the Earth's crust (Polyak and Smirnov, 1966; etc.). «Heat flow-age dependence» indicates unknown temporal heat sources in the interior consid

The isotopic composition of helium ( 3 He 4 He = R ) contained in underground fluids was studied in different geotectonic provinces. Provincial mean values ( R ) were estimated by a routine statistic procedure. The R - values were found to depend on
