TLDR
Some eclogitic and ultrabasic inclusions, their separated minerals, host rocks, and related samples have been analyzed by mass-spectrometric isotope dilution for K, Rb, Sr, Ba and rare-earth elements (RE), and by other techniques for selected major elements as discussed by the authors.About:

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.

Anhydrous melting of peridotite at 0–15 Kb pressure and the genesis of tholeiitic basalts
A. L. Jaques,David H. Green +1 more
TL;DR: In this paper, the anhydrous melting behavior of two synthetic peridotite compositions has been studied experimentally at temperatures ranging from near the solidus to about 200°C above the core within the pressure range 0-15 kb.

Ultramafic inclusions from San Carlos, Arizona: Petrologic and geochemical data bearing on their petrogenesis
Frederick A. Frey,Martin Prinz +1 more
TL;DR: In this article, the authors classified ultramafic inclusions from San Carlos, Arizona into two groups: Group I inclusions are dominated by magnesian (Mg/Mg + ΣFe= 0.86-0.91), olivine-rich peridotites containing Cr-rich clinopyroxene and spinel.

143Nd/146Nd, a natural tracer: an application to oceanic basalts*
TL;DR: In this paper, the possibility of using 143Nd/146Nd as a natural tracer was examined by analyzing two Hercynian granitic rocks, one carbonatite, three alkali basalts and nine tholeiites.

Quantitative models of trace element behavior in magmatic processes
Claude J. Allègre,J. F. Minster +1 more
TL;DR: In this paper, the present status of the utilization of trace elements in igneous processes, which acknowledges the deep-seated conviction of Paul Gast that the trace element approach was at least as powerful as experimental petrology to solve the major petrological problems.

Trace element fractionation and the origin of tholeiitic and alkaline magma types
TL;DR: In this article, it was shown that the abundance of large ion elements in alkaline basalts cannot be consistently explained by fractional crystallization processes and that these characteristics are produced by previous partial melting episodes.

Partition coefficients of rare-earth elements between igneous matrix material and rock-forming mineral phenocrysts—II
TL;DR: In this paper, solid-liquid partition coefficients between phenocrysts and the host lavas have been measured for rare-earth elements by an isotope dilution technique and the consistency of much of the data suggests that most of the phenocryst crystallized under equilibrium, or quasi-equilibrium, conditions.

Chemical Characteristics and Origin of Oceanic Ridge Volcanic Rocks
TL;DR: Oceanic ridge volcanic rocks alkali metal, alkaline earth, rare earth, nickel and major element content, observing partial melting as mentioned in this paper. But this is not the case for all volcanic rocks.
