Crust-mantle interaction induced by deep subduction of the continental crust: geochemical and Sr-Nd isotopic evidence from post-collisional mafic-ultramafic intrusions of the northern Dabie complex, central China
TLDR
In this article, geochemical and isotope tracer analyses of postcollisional mafic-ultramafic rocks from the Dabie terrane in central China show that they could have been generated by melting of such metasomatized mantle as a result of crust-mantle interaction.About:

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.

Stable isotope geochemistry of ultrahigh pressure metamorphic rocks from the Dabie–Sulu orogen in China: implications for geodynamics and fluid regime
TL;DR: In this article, a fried ice cream model was proposed to explain the rapid processes of both plate subduction and exhumation, with a short residence time of the UHP slab at mantle depths.

Mesozoic lithosphere destruction beneath the North China Craton: evidence from major-, trace-element and Sr–Nd–Pb isotope studies of Fangcheng basalts
TL;DR: The Mesozoic Fangcheng basalts as discussed by the authorseng et al. showed that these basalts are extremely enriched in LREEs ((La/Yb)N=39.3-49.3) and LILEs (Ce, Rb, Ba, U, Th), with slightly negative Pb anomaly.

Highly evolved juvenile granites with tetrad REE patterns: the Woduhe and Baerzhe granites from the Great Xing'an Mountains in NE China
TL;DR: In this paper, the ages of two highly evolved granitic plutons, Woduhe and Baerzhe, from the Great Xing'an Mountains were constrained at 130±4 Ma for the Wodahe and 122±5 Ma for BaerZhe granites by Rb-Sr and Sm-Nd isotope analyses.

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.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.

Derivation of some modern arc magmas by melting of young subducted lithosphere
Marc J. Defant,Mark S. Drummond +1 more
TL;DR: In this paper, the trace-element geochemical properties of the adakites (termed "adakites") of modern island and continental arcs are shown to be consistent with a derivation by partial melting of the subducted slab, and in particular that subducting lithosphere younger than 25 Myr seems to be required for slab melting to occur.

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.
