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 ...

Tantal-Niobium Minerals of the Upper Riphean Fedotovskaya Suite (the Middle Urals)

Вестник Пермского университета. Геология, 2019
The petrographic peculiarities of the Fedotovskaya Suite of the Upper Riphean in the western slope of the Middle Urals are considered. The mineral varieties of tantal-niobium components (ilmenorutile, tantalorutile, yttrocolumbite, polycrase) and geochemical regularities in distribution of niobium concentrations in well sections are described.
