U-Pb age and trace elements composition of titanite from granites of Belokurikhinsky massif, Gorny Altai

open access: yesVestnik MGTU, 2021
As a result of isotope-geochemical study, the age data (U-Pb method, ID-TIMS) of titanite from the first phase granites of the Belokurikhinsky granite massif, Gorny Altai, were obtained for the first time. The concordant value of the titanite age of 255 ±

Mineralogy of the inclusions and age of zircon from granite basement of Verkhnerechensk area (Yamal peninsula)

open access: yesЛитосфера, 2017
The study of minerals-prisoners in accessory zircons is gradually evolving into an important geological-petrological task. Such a study can show not only the earliest mineral rock association, but also evaluate the “sealed” mineral paragenesis of zircon,

Murzinka massive at the middle urals as an example of the interformational granite pluton: magmatic sources, geochemical zonality, peculiarities of formation

open access: yesЛитосфера, 2018
Murzinka massif is a sheet-like interformational body steeply deeping to the East with length about 6 km. Proterozoic metamorphic rocks of the predominantly granulite facies ( P = 5-6 kbar, T = 750-800°C) occur at the base of massif, and volcanic ...

The plume-dependent granite-rhyolite magmatism

open access: yesЛитосфера, 2018
The plume-dependent magmatism is widespread and well justified. The bulk of it is represented by flood basalts, basalts of oceanic islands (OIB), and basalts of oceanic plateaus (OPB), though the whole scope of plume magmatism is very diverse.

Postmagmatiс tectonics of granites and morphostructure the Northern Tien Shan

open access: yesЛитосфера, 2016
The granites are represented significant volumes (up to 50% or more) of the continental upper crust, and, certainly, they should influence on the formation of the crust structure and peculiarities of its evolution. Is generally assumed that after cooling
