TLDR
Granulite xenoliths sampled from the Hannuoba basalts, North China craton, allow recognition of three types of ancient lower crustal components as discussed by the authors, including felsic granulite-facies metamorphism.About:

Continental and Oceanic Crust Recycling-induced Melt^Peridotite Interactions in the Trans-North China Orogen: U^Pb Dating, Hf Isotopes and Trace Elements in Zircons from Mantle Xenoliths
TL;DR: In this article, the first finding of continental crust-derived Precambrian zircons in garnet/spinel pyroxenite veins within mantle xenoliths carried by the Neogene Hannuoba basalt in the central zone of the North China Craton (NCC).

Nature and significance of the Early Cretaceous giant igneous event in eastern China
TL;DR: In this article, Zhang et al. used zircon U-Pb SHRIMP (5 samples), laser ablation (LA) ICP-MS (22 samples), and TIMS (5 sample) dating to establish that the Early Cretaceous was a significant period of igneous activity in the Liaodong Peninsula, with a duration of about 10 Ma.

Integration of geology, geophysics and geochemistry: A key to understanding the North China Craton
TL;DR: In this paper, the authors studied the North China Craton (NCC) at the end of the Pre-Cambrian and revealed decoupling brought about by repeated orogenic events over the history of NCC.

Late Mesozoic volcanism in the Great Xing'an Range (NE China): Timing and implications for the dynamic setting of NE Asia
TL;DR: In this article, a shears-shaped lithospheric delamination mechanism is proposed to construe the geodynamic scenario of northeastern Asia during Late Mesozoic: the collision between north China and Siberia around ∼Â160 ǫ Ma obstructed the westwards movement of the lithosphere induced by the subduction of Pacific plate, this tremendous stress caused the thickened lithosphere delaminating from west edge of the northeast China-Mongolia block at ∼Â 160 ǔ Ma and extended gradually eastwards, resulting volcanism migration from west to east in northeastern

Lithium isotopic composition and concentration of the upper continental crust
Fang-Zhen Teng,William F. McDonough,Roberta L. Rudnick,Claude Dalpé,Claude Dalpé,Paul B. Tomascak,Bruce W. Chappell,Shan Gao,Shan Gao +8 more
TL;DR: The Li isotopic composition of the upper continental crust is estimated from the analyses of well-characterized shales, loess, granites and upper crustal composites from North America, China, Europe, Australia and New Zealand as mentioned in this paper.

M. Wiedenbeck,P. Allé,Fernando Corfu,William L. Griffin,M. Meier,F. Oberli,A. von Quadt,J.C. Roddick,W. Spiegel +8 more
TL;DR: In this paper, the results of a study to develop natural zircon geochemical standards for calibrating the U-(Th)-Pb geochronometer and Hf isotopic analyses are reported.

The Composition of Zircon and Igneous and Metamorphic Petrogenesis
Paul W.O. Hoskin,Urs Schaltegger +1 more
TL;DR: The importance of zircon in crustal evolution studies is underscored by its predominant use in U-Th-Pb geochronology and investigations of the temporal evolution of both the crust and lithospheric mantle as discussed by the authors.

Correction of common lead in U-Pb analyses that do not report 204Pb
TL;DR: In this article, the authors proposed a correction method that neither uses 204Pb nor assumes concordance, but uses a numeric solution to a set of equations relating the content of radiogenic lead in a zircon or other U/Th-enriched mineral to its total lead content.

Atlas of Zircon Textures
TL;DR: In this paper, a selection of both the most typical, but also of the less common, features seen in zircon, categorized according to the different geological processes responsible for their formation are presented.

Trace element and isotopic effects of combined wallrock assimilation and fractional crystallization
TL;DR: In this paper, the mass assimilation rate is an arbitrary fraction(r) of the fractional crystallization rate, where r < 1 is a combination of zone refining and fractional scaling.
