TLDR
In this article, it is suggested that massive mixing processes occur near the base of the continental crust when mantle magmas are ponded near the Moho interface and this process is responsible for the general geochemistry of granitic magmas.About:

Major and trace element composition of the depleted MORB mantle (DMM)
R. Workman,Stanley R. Hart +1 more
TL;DR: Asimow et al. as mentioned in this paper derived an estimate for the chemical composition of the depleted MORB mantle (DMM), the source reservoir to mid-ocean ridge basalts (MORBs), which represents at least 30% the mass of the whole silicate Earth.
Journal ArticleDOI
A model for Trondhjemite-Tonalite-Dacite Genesis and crustal growth via slab melting: Archean to modern comparisons
Mark S. Drummond,Marc J. Defant +1 more
TL;DR: In this paper, the authors introduced the importance of subducted oceanic crustal age on arc petrogenesis and demonstrated that Archean TTD crustal generation processes are also present in selected high-Al Phanerozoic TTD terranes.
Journal ArticleDOI
Evolution of the depleted mantle: Hf isotope evidence from juvenile rocks through time
TL;DR: In this article, the covariant behavior of Lu-Hf and Sm-Nd isotopes during most magmatic processes has been recognized, but the details of this behavior in the depleted mantle reservoir have not been adequately examined.
Journal ArticleDOI
Accretionary orogens through Earth history
Peter A. Cawood,Alfred Kröner,William J. Collins,Timothy M. Kusky,Walter D. Mooney,Brian F. Windley +5 more
TL;DR: In this paper, the authors classify orogens into retreating and advancing types, based on their kinematic framework and resulting geological character, including the supra-subduction zone forearc, magmatic arc and back-arc components.

Temperatures in Ambient Mantle and Plumes: Constraints from Basalts, Picrites, and Komatiites
Claude Herzberg,Paul D. Asimow,Nicholas Arndt,Yaoling Niu,C. M. Lesher,J. G. Fitton,Michael J. Cheadle,Ad D. Saunders +7 more
TL;DR: In this paper, a new evaluation is made of parental magma compositions that would crystallize olivines with the maximum forsterite contents observed in lava flows, consistent with the plume model.

Mountain belts and the new global tectonics
John F. Dewey,John M. Bird +1 more
TL;DR: In this paper, it is proposed that mountain belts develop by deformation and metamorphism of the sedimentary and volcanic assemblages of Atlantic-type continental margins, resulting from the events associated with the rupture of continents and the expansion of oceans by plate generation at oceanic ridges.

Seismology and the new global tectonics
TL;DR: In this article, a comprehensive study of the observations of seismology provides widely based strong support for the new global tectonics which is founded on the hypotheses of continental drift, sea-floor spreading, transform faults and underthrusting of the lithosphere at island arcs.
