TLDR
Two syenite-granite suites, metaluminous and peralkaline, that form the Bryansky Complex in Transbaikalia, Russia, have been studied with the aim to constrain the existing models of A-type granitoid magma generation.About:

Geochronology of the Phanerozoic granitoids in northeastern China
TL;DR: Zhang et al. as mentioned in this paper used zircon U-Pb dating to constrain the spatial and temporal distribution of granitoids in the area. But the results showed that granitoid emplacement dates are not as widely distributed as previously thought.

The Central Asian orogenic belt and growth of the continental crust in the Phanerozoic
TL;DR: Using the Nd-Sr isotope tracer technique, the majority of granitoids from the Central Asian Orogenic Belt (CAOB) can be shown to contain high proportions (60 to 100%) of the mantle component in their generation as discussed by the authors.

A hybrid origin for the Qianshan A-type granite, northeast China: Geochemical and Sr–Nd–Hf isotopic evidence
TL;DR: In this paper, a suite of A-type granites and mafic microgranular enclaves from the Early Cretaceous (126 −± 2 Ma) Qianshan pluton, Liaodong Peninsula, northeast China, were investigated.

Zircon age and occurrence of the Adaatsag ophiolite and Muron shear zone, central Mongolia: constraints on the evolution of the Mongol–Okhotsk ocean, suture and orogen
TL;DR: The Adaatsag ophiolite in eastern Mongolia is situated in the Mongol-Okhotsk suture zone, which extends from central Mongolia through Transbaikalia to the Sea of Okhotsk and separates the Siberian and Amurian (Mongolian) plates as discussed by the authors.

TL;DR: The Beishan orogenic collage was previously regarded as early Paleozoic in age in contrast to the surrounding southern Altaid collages, which are Late Permian or even Early Mesozoic as mentioned in this paper.

Chemical and isotopic systematics of oceanic basalt : implications for mantle composition and processes
TL;DR: In this article, trace-element data for mid-ocean ridge basalts and ocean island basalts are used to formulate chemical systematics for oceanic basalts, interpreted in terms of partial-melting conditions, variations in residual mineralogy, involvement of subducted sediment, recycling of oceanic lithosphere and processes within the low velocity zone.

Approximation of terrestrial lead isotope evolution by a two-stage model
J.S. Stacey,Jan Kramers +1 more
TL;DR: In this paper, a two-stage model for terrestrial lead isotope evolution is proposed, which permits the age of the earth to be that of the meteorite system and also yields good model ages for samples of all ages.

A-type granites: geochemical characteristics, discrimination and petrogenesis
TL;DR: A-type granites as mentioned in this paper were found to have high SiO2, Na2O+K2O, Fe/Mg, Ga/Al, Zr, Nb, Ga, Y and Ce, and low CaO and Sr.
