Rare earth elements and the island arc tholeiitic series
P. Jakesˇ,James B. Gill +1 more
TLDR
The island arc tholeiitic series as mentioned in this paper is the most dominant in many western Pacific and Atlantic Island arcs and represents the earliest stages in arc evolution. But it is chemically inappropriate to call many of the rocks in island arcs calc-alkaline and they suggest they be known as the "island arc thoeitic series" and they differ from normal thoeiitic features by having a higher percentage of intermediate and acid members and too little normative olivine, for example, to have been in equilibrium with peridotite.About:

The petrochemistry of ophiolite gabbroic complexes. A key for the classification of ophiolites into low-Ti and high-Ti types
TL;DR: In this paper, the fractionation trends of both gabbroic complexes and lavas and dykes were studied in the TiO2/M.I. diagram, and parental magmas and fractionation processes of low-Ti ophiolites fit with an hypothesis of their formation in the early stage of opening of intra-oceanic back-arc basins.

Role of trace element partition coefficients in models of andesite genesis
TL;DR: In this paper, the trace element concentration data for orogenic andesites in general or for most specific suites is not possible using available partition coefficients, and therefore it is necessary to use a more rigorous data base than presently available.

Timescale for producing the geochemical signature of island arc magmas: U-Th-Po and Be-B systematics in recent Papua New Guinea lavas
TL;DR: U-series activities, beryllium isotopes and boron abundances are reported for twenty samples from fourteen Holocene volcanic centers in Papua New Guinea, spanning several tectonic settings as mentioned in this paper.

Early Geochemical Evolution of an Oceanic Island Arc and Backarc: Fiji and the South Fiji Basin
TL;DR: The early arc stage of oceanic arc volcanism in Fiji was dominated by low-K tholeiitic basalts and andesites with flat REE patterns as low as 4x chondritic concentrations.

Distribution of the Elements in Some Major Units of the Earth's Crust
Karl K. Turekian,K. H. Wedepohl +1 more
TL;DR: A table of abundances of the elements in the various major units of the Earth's lithic crust with a documentation of the sources and a discussion of the choice of units and data is presented in this article.

The genesis of basaltic magmas
David H. Green,A.E. Ringwood +1 more
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.
Journal ArticleDOI
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.
Journal ArticleDOI
Chemical Characteristics of Oceanic Basalts and the Upper Mantle
TL;DR: In this article, it was shown that oceanic tholeiites are either complete melts of the upper mantle or are generated from a mix of this tholeite and a magnesium-rich peridotite or dunite in proportions up to perhaps 1:4.
Journal ArticleDOI
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.
