'Diffusive' border of isotopic reservoirs of indian and pacific morb types beneath Kamchatka

Publikováno v: Доклады Академии наук. 486:691-694

The convergence zones of lithospheric plates in the Northwest Pacific are the boundaries of the two main isotopic domains of the Earth - the Indian and Pacific MORB types, separated be cold oceanic lithosphere. This configuration limits of their inte

The Diffusive Boundary of Isotopic Reservoirs of the Indian and Pacific MORB types beneath Kamchatka

Autor: Yu. A. Martynov, M. Yu. Davydova

Publikováno v: Doklady Earth Sciences. 486:623-626

The key role of asthenospheric diapirism in the origin of the diffusive boundary of isotopic reservoirs of the Indian and Pacific MORB types was shown on the basis of high-precision Pb data. In view of the fact that the described processes are not un
