.../Yb) n and Sr/Y ratios, and the low-alumina TT show quite an opposite pattern. The figurative points of plagiogranites from the Kuvai massif lie near the tentative boundaries of the fields of high- and low-alumina TT. This is accounted for by the leucocratic composition of the rocks. It is obvious...

... is gradually supplemented with the terrigene rocks of the Zhistyk Formation and the lower Anastas’ino Formation. At the bottom of the sections of these formations (see Fig. 2 /2), there is a basal coarse-clastic member of “Grebeshkovo” conglomerates, which overlie volcanosedimentary deposits of the Kuvai...

...S.N. Rudnev; A.S. Gibsher; D.V. Semenova Abstract —Based on new geochronological data on gabbroid and plagiogranitoid associations (Tavan-Hayrhan, East Bayan Tsagaan, Bayan Tsagaan Uul, Tungalag, Three Hills, and Shutkhuin massifs) located among the Vendian island-arc volcanic complexes of the Lake...

... of the events that occurred in the Baikal-Vitim SFD. Their most likely cause was the starting subduction of an oceanic block beneath a continental one. In a similar way, during the Baikalian, the Stanovoy microcontinent shifted northward along a suture dipping under the Aldan Massif [ 27 ]. Next burst...

... and indicate that these rocks were deposited before the emplacement of postcollisional granites of the Taraka massif and thus predate the major orogenic events within the Angara–Kan block. Therefore, these rocks can be correlated with the lower part of the Urik–Iya graben section. The metamorphic rocks from...
