TLDR
Alkaline granites (RbSr ages 276-286 Ma) occur in the Baiyinula-Dongujumqin belt of the southern margin of the Siberian plate, and were generated in tensional tectonic environments.About:

Accretion leading to collision and the Permian Solonker suture, Inner Mongolia, China: Termination of the central Asian orogenic belt
TL;DR: In this paper, the authors report new field data for the Ondor Sum melange in the Ulan valley, and present a new evaluation of the orogenic belt extending from the southern Mongolia cratonic boundary to the north China craton.
Journal ArticleDOI
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.

A-type granites in northeastern China: age and geochemical constraints on their petrogenesis
TL;DR: A-type granites are widely distributed in northeastern China (NE China). They were emplaced during three major episodes (the Permian, late Triassic to early Jurassic, and early Cretaceous) and evolved in different tectonic regimes.
Journal ArticleDOI
Granitoids of the Central Asian Orogenic Belt and Continental Growth in the Phanerozoic
TL;DR: Most Phanerozoic granitoids of Central Asia are characterised by low initial Sr isotopic ratios, positive eNd(T) values and young Sm-Nd model ages (TDM) of 300-1200 Ma.

Permian geodynamic setting of Northeast China and adjacent regions: closure of the Paleo-Asian Ocean and subduction of the Paleo-Pacific Plate
TL;DR: In this paper, a comprehensive analysis of available geological, geochemical, paleobiogeographical and paleomagnetic data is presented, based on which it is shown that the Permian marine basins in northeast China and adjacent regions include remnants of the Paleo-Asian Ocean in southeastern Inner Mongolia and central Jilin Province.

Trace element discrimination diagrams for the tectonic interpretation of granitic rocks
TL;DR: In this article, a data bank containing over 600 high quality trace element analyses of granites from known settings was used to demonstrate using ORG-normalized geochemical patterns and element-SiO2 plots that most of these granite groups exhibit distinctive trace element characteristics.
Journal ArticleDOI
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.
Journal ArticleDOI
Petrogenetic interpretation of granitoid rock series using multicationic parameters
TL;DR: In this paper, the authors suggest that most granitoid series result from a two-stage process, first fractional crystallisation of clinopyroxene, olivine and calcic plagioclase from a basic source with tholeiitic affinities produces a magma of intermediate composition.
Journal ArticleDOI
Post-Collisional Alkaline Granites
TL;DR: Alkaline granites that may have formed in postcollisional plate tectonic environments are present in the Alaskan Cordillera, the New England and Lachlan Fold Belts of Australia, and the Arabian-Nubian Shield as mentioned in this paper.
