An experimental study of Nb and Ta partitioning between Ti-rich minerals and silicate liquids at high pressure and temperature
TLDR
In this paper, an experimental determination of partition coefficients (D) for Nb and Ta between Ti-rich minerals (sphene, rutile, ilmenite and Ti-magnetite) and coexisting silicate liquids of basaltic andesite and trachyte composition was performed.About:

Chemical differentiation of the Earth: the relationship between mantle, continental crust, and oceanic crust
TL;DR: In this paper, the average chemical compositions of the continental crust and the oceanic crust (represented by MORB), normalized to primitive mantle values and plotted as functions of the apparent bulk partition coefficient of each element, form surprisingly simple, complementary concentration patterns.

An overview of adakite, tonalite–trondhjemite–granodiorite (TTG), and sanukitoid: relationships and some implications for crustal evolution
TL;DR: In this article, an analysis of an extensive adakite geochemical database identifies two distinct compositional groups: high-SiO2 adakites (HSA) which represent subducted basaltic slab-melts that have reacted with peridotite during ascent through mantle wedge and low-Si O 2 adakitic mantle wedge.

Chemical subdivision of the A-type granitoids:Petrogenetic and tectonic implications
TL;DR: The A-type granitoids can be divided into two chemical groups as mentioned in this paper : oceanic-island basalts and island-arc basalts, and these two types have very different sources and tectonic settings.

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.

The A-type granitoids: A review of their occurrence and chemical characteristics and speculations on their petrogenesis
TL;DR: The A-type granitoid suites vary in composition from quartz syenites to peralkaline granites and their respective volcanic equivalents as mentioned in this paper, and the A-types are characterized by their relatively high alkali contents and low CaO contents.

Petrogenetic implications of Ti, Zr, Y, and Nb variations in volcanic rocks
TL;DR: In this paper, a table of mineral-liquid distribution coefficients for Ti, Zr, Y, and Nb for basic, intermediate and acid melt compositions were used to interpret variations of these elements, first in basalts and second during fractional crystallization from basic to acid magmas.

Empirical Correction Factors for the Electron Microanalysis of Silicates and Oxides
A. E. Bence,Arden L. Albee +1 more
TL;DR: In this paper, the calibration curve in a binary metal alloy system can, within the variance of data points, be described by the linear expression $$C_{A}/K{A} = \alpha_{AB} + (1 - α_{AB})C{A]$$, where C is the concentration of element A in alloy  relative to pure A, and K is the background-corrected intensity of a characteristic radiation line of A in the alloy relative to that of pure A. This linear variation of the correction factor with composition can be extended to multicomp

TL;DR: In this paper, the results of a detailed experimental investigation of fractionation of natural basaltic compositions under conditions of high pressure and high temperature were reported, where a single stage, pistoncylinder apparatus has been used in the pressure range up to 27 kb and at temperatures up to 1500° C to study the melting behaviour of several basaltics compositions.
