PETROGENESIS OF S-TYPE GRANITOID MAGMATISM ON THE MARGIN OF THE TUVA-MONGOLIAN MASSIF (WESTERN SANGILEN, SOUTHEASTERN TUVA): SETTINGS, AGE, AND FORMATION STAGES

Геодинамика и тектонофизика
This study integrates the isotope-geochronological (zircon U-Pb dating), petrogeochemical and structural-petrological data, as well as the data on garnet composition and fluid inclusions in leucogranite quartz, to characterize S-type granitoid magmatism ...

The age and origin of alkaline rocks of the Dakhunur pluton, South-Eastern Tuva

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019
The research is aimed at proving the age, nature of parental magma sources, and geodynamic conditions, under which alkaline intrusives of the Tuva Mongolian terrain were introduced. That is relevant when reconstructing development of the Paleoasian Ocean

(Table) Argon isotope ratios and argon ages of rocks obtained from the Chernorud zone, western Baikal area

, 2009
Structural-petrologic and isotopic-geochronologic data on magmatic, metamorphic, and metasomatic rocks from the Chernorud zone were used to reproduce the multistage history of their exhumation to upper crustal levels.

Metacarbonate-terrigenous complex of the Derba block (East Sayan): petrogeochemical and isotope parameters, metamorphism, and time of formation

, 2018
The Derba block is one of the largest Precambrian terranes of the Sayan–Yenisei accretionary belt in the southwestern margin of the Siberian Platform. It is composed of metamorphosed terrigenous-carbonate rocks of the Sayan Group, injected by granitoids.

Relationship between the fractal dimension of orthopyroxene distribution and the temperature in mantle xenoliths

, 2016
As rock textures reflect the physical conditions and the mechanisms of formation of the rocks, new approaches are used for improving texture analyses, both qualitatively and quantitatively.
