THERMODYNAMIC RIPHEAN-PHANEROZOIC EVOLUTION OF THE UPPER GEOSPHERES: ATMOSPHERE, EARTH’S CRUST, HYDROSPHERE AND BIOSPHERE [PDF]

Geological Journal, 2020
A new concept of thermodynamic Riphean-Phanerozoic evolution of upper geospheres: atmosphere, earth’s crust, hydrosphere and biosphere is presented. This evolution from Riphean to Phanerozoic is determined by the consistent cooling of the earth’s surface.

Zircon as a Source of Genetic Information in Upper Riphean Terrigenous Deposits of Southern Timan

The Bulletin of Irkutsk State University. Series Earth Sciences, 2023
Zircon is an important source of genetic information. The purpose of the research is a detailed study, identification of diagnostic features, and determination of the evolution of the composition of zircon, which will make it possible to establish the sources of clastic material and the conditions for the formation of the paleontologically mute ...
