Journal ArticleDOI
Granite: From genesis to emplacement
TL;DR: In this paper, phase diagrams for pelite are used to illustrate the mineralogical controls on melt production and the consequences of different clockwise pressure-temperature (P - T ) paths on melt composition.
Journal ArticleDOI
Highly fractionated granites: Recognition and research
TL;DR: In this article, the authors proposed that granites are an important sign indicating compositional maturity of the continental crust, and they are also closely related to the rare-elemental (metal) mineralization of W, Sn, Nb, Ta, Li, Be, Rb, Cs, REEs, etc.

Partial melting of lower crust at 10–15 kbar: constraints on adakite and TTG formation
TL;DR: In this article, the authors have carried out partial melting experiments of mafic lower crust in the piston-cylinder apparatus at 10-15-kbar and 800-1,050-°C to investigate the major and trace elements of melts and residual minerals and further constrain the pressure-temperature (P-T) range appropriate for adakite/TTG formation.
Journal ArticleDOI
Experimental melts from crustal rocks: A lithochemical constraint on granite petrogenesis
TL;DR: In this paper, a compilation and synthesis of available experimental data for the major element compositions of felsic melts derived from partial melting of natural or synthetic materials in the compositional range of crustal rocks is presented.

Magmatic evolution and crustal recycling for Neoproterozoic strongly peraluminous granitoids from southern China: Hf and O isotopes in zircon
Xiao-Lei Wang,Xiao-Lei Wang,Jin-Cheng Zhou,Yu-Sheng Wan,Kouki Kitajima,Di Wang,Chloë E. Bonamici,Jiansheng Qiu,Tao Sun +8 more
TL;DR: In this paper, a negative correlation of Th/U versus d 18 O is found for most analyses, indicating a dramatic shift toward higher oxygen isotope values by voluminous partial melting of supracrustal rocks and signaling a transition from I-type to S-type-like magmas during the later stage of magmatic evolution.

Journal ArticleDOI
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.
Journal ArticleDOI
Crustal contributions to arc magmatism in the Andes of Central Chile
Wes Hildreth,Stephen Moorbath +1 more
TL;DR: In this article, 15 andesite-dacite stratovolcanoes on the volcanic front of a single segment of the Andean arc show along-arc changes in isotopic and elemental ratios that demonstrate large crustal contributions to magma genesis.
Journal ArticleDOI
The Genesis of Intermediate and Silicic Magmas in Deep Crustal Hot Zones
TL;DR: In this article, a model for the generation of intermediate and silicic igneous rocks is presented, based on experimental data and numerical modeling, which is directed at subduction-related magmatism, but has general applicability to magmas generated in other plate tectonic settings, including continental rift zones.
