TLDR
In a high-pressure experimental study of reactions and possible melt products occurring in the deep continental crust or in subducted oceanic crust, sphene has been identified over a pressure range of 10-18 kbar and to temperatures of 1020°C as discussed by the authors.

A model for Trondhjemite-Tonalite-Dacite Genesis and crustal growth via slab melting: Archean to modern comparisons

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.

Migration of fluid phases and genesis of basalt magmas in subduction zones

TL;DR: In this paper, the role of H2O in the production of arc magmas at convergent plate boundaries was examined in both the downgoing lithosphere and the overlying mantle wedge.

Chemical characteristics of island-arc basalts: Implications for mantle sources

TL;DR: In this article, the major-element, trace-element and isotopic compositions of approximately 1200 basalts (Mg +Fe 2+ ) > 65 ] IAB and MORB are similar, but differ significantly from IPB.

Rutile saturation in magmas: implications for TiNbTa depletion in island-arc basalts

TL;DR: In this paper, the authors investigated the properties of rutile-saturated melts ranging from basalt to rhyodacite and found that dissolved TiO 2 is positively correlated with T and not strongly dependent on P total.

Geochemistry of eocene calc-alkaline volcanic rocks from the Kastamonu area, Northern Turkey

TL;DR: In this paper, the Pontic eocene volcanic rocks cropping out in the Kastamonu area, Pontic chain of Northern Turkey were analyzed and the SiO2% versus K2O% relationship showed that the analyzed samples belong to two major groups: the basaltic andesitic and the andesite ones.

Relative and Absolute Terrestrial Abundances of the Rare Earths

TL;DR: In this article, the relative rare-earth abundances in composite samples of shales, metamorphosed shales and chondritic meteorites are reported, showing that common crustal rocks are deficient in Eu, relative to the other rare earths.
Journal ArticleDOI

The application of trace elements to the petrogenesis of igneous rocks of granitic composition

TL;DR: In this article, the effects of these minerals on the rare earth elements (REE) patterns of granitic melts during partial melting or differentiation are exaggerated as compared to basaltic systems, making detection of residual phases easier.
