Methods of isotopic geology and the geochronological scale
Abstract
The book presents an overview of the isotopic geochronology methods used in the USSR presently, with special consideration given to the discussion of the comparative value of the U-Pb, Rb-Sr, Sm-Nd, and K-Ar methods. New chronological data are presented for the Ukrainian and the Aldan-Vitim shields, the eastern part of the Baltic shield, and a stratified structure in the Tian Shan mountains. The geochronological scale of the upper Proterozoic formations and the geochronologic boundary of the Phanerozoic formations are discussed.
