Heat and mass transfer from the mantle: heat flow and He-isotope constraints

Autor: B. G. Polyak

Publikováno v: Annals of Geophysics, Vol 48, Iss 1 (2005)

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 cons

Ascending Heat and Mass Flow in Continental Crust: on the Problem of Driving Forces of Tectogenesis

Autor: B. G. Polyak, M. D. Khutorskoi, I. N. Tolstikhin

Publikováno v: Izvestiya, Physics of the Solid Earth. 56:490-510

The geophysical and geochemical indicators of the ascending heat and mass flow in the continental crust—conductive heat flow through the surface of the crust and the isotopic composition of helium in freely circulating underground fluids—are cons

Isotope-Geochemical Features and Genesis of Gases in the East Carpathian Region

Autor: I. L. Kamensky, B. G. Polyak, A. L. Cheshko, O. E. Kikvadze, E. M. Prasolov

Publikováno v: Lithology and Mineral Resources. 53:380-393

The paper presents data on the composition of a gas phase of underground fluids in the East Carpathian region, including 3He/4He, 40Ar/36Ar, and 4He/20Ne ratios. The argon isotope composition of these gases was used to estimate the fractions of atmos

Helium isotope studies of the Central Tien Shan

Autor: B G Polyak, E A Bataleva, A K Rybin

Publikováno v: IOP Conference Series: Earth and Environmental Science. 929:012005

The research shows new results of isotope-helium studies carried out in the Tien Shan - Naryn and Atbashi basins. Sampling of thermal mineral springs in the Eastern Tien Shan was carried out in order to identify traces of mantle emanations in fluids

Autor: M. D. Khutorskoi, B. G. Polyak

Publikováno v: Geotectonics. 50:179-195

Heat generation due to decay of long-lived radioactive isotopes is considered in the Earth’s crust of the Archean–Proterozoic and Paleozoic provinces of Eurasia and North America. The heat flow that forms in the mantle is calculated as the differ
