| Abstract | As an indicator of crust-mantle interaction, helium isotopic composition (He/He =R) in subsurface fluids was studied in the East European segments of the Alpine Himalayan fold belt, in Baikal rift zone, and in the Transmexican volcanic belt, as well as in the adjacent areas. The R-value distribution correlates with tectonic pattern, magmatic manifestations and their Sr-isotope marks, background heat flow density and the lithosphere thickness. |
