..., with significant overlap in time (281–276 Ma), by emplacement of Early Kunalei suite of alkaline (alkali feldspar) and peralkaline syenite and granite. Concurrent emplacement of distinct plutonic suites suggests simultaneous magma generation at different depth and, possibly, from different sources. Despite complex...

Dashed-line contours – Early Permian granitoid plutons (Lower-Selenga suite). Black spots – plutons of alkali-feldspathic and alkali granitoids (Kudun and Kunalei suites). Plutons: 1...

... through transitional from calc-alkaline to alkaline granites and quartz syenites (Zaza complex) at the intermediate stage to peralkaline granitoids (Early Kunalei complex) at the last stage. This evolution trend is complicated by the synchronous development of granitoid complexes with different sets...

...; it lasted at least 10–12 Myr and was apparently related to the repeated intrusion of large volumes of salic magmas and the formation of granitoid plutons. Early Mesozoic composite dikes associated with alkali-granitoid plutons of the Late Kunalei igneous complex (230–210 Ma) are much scarcer. Basic magmas...

..., formed, and (2) 310–270 Ma, when most AVB granitoids formed. We suggest that at the early stage, crustal peraluminous granites formed in collision geodynamic setting. At the late (main) stage, magmatism occurred in postorogenic-extension setting and was accompanied by the formation of several geochemical...

... spread in its eastern part are exposed at the foot of Zusa Range in the north and Kudunsky in the south. They overlap granitoids of the Late Paleozoic Bryansky and Early Mesozoic Malyi Kunaley complexes. This is where they overlap granitoids of the Late Paleozoic Bryansky and Early Mesozoic Malyi Kunaley...

Late Mesozoic rifting did not change the general structure of the Early Mesozoic rift zone. However, it gave rise to a new system of horsts and grabens, which are well-pronounced...
