TLDR
Partition coefficients for K, Rb, Sr, and Ba distributed between plagioclase, K-feldspar, clinopyroxene, orthopyroxenes, mica, hornblende, garnet, and olivine phenocrysts and their igneous matrix materials, have been determined by a mass-spectrometric stable isotope dilution technique.About:

Chemical and isotopic systematics of oceanic basalt : implications for mantle composition and processes
TL;DR: In this article, trace-element data for mid-ocean ridge basalts and ocean island basalts are used to formulate chemical systematics for oceanic basalts, interpreted in terms of partial-melting conditions, variations in residual mineralogy, involvement of subducted sediment, recycling of oceanic lithosphere and processes within the low velocity zone.

Aleutian magnesian andesites: Melts from subducted Pacific ocean crust
TL;DR: In this article, a small amount of partial melting of subducted Pacific ocean crust (basalt) consisting mainly of garnet and clinopyroxene (eclogite or garnet websterite) is proposed.

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.

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.

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.

Trace element partition between two pyroxenes and the host lava
TL;DR: Partition coefficients for +1, +2, +3 and +4 valent trace ions between alkaline olivine basalt lava and the coexisting ortho- and clinopyroxene phenocrysts from Takashima, North Kyushu, Japan, have been determined by neutron activation analysis as mentioned in this paper.

Trace element partition coefficients—a review of theory and applications to geology
TL;DR: In this article, the thermodynamics of trace element partition among coexisting phases is reviewed and the effect of temperature, pressure and phase composition on the numerical value of D is discussed.
