Rare earth elements and the island arc tholeiitic series

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 origin of the Naturaliste Plateau, SE Indian Ocean: Implications from dredged basalts
TL;DR: A re-examination of the dredge haul shows that the rock clasts are in fact altered tholeiitic basalts as discussed by the authors, which have affinities both with MOR basalts and especially with within-plate basalts.
Journal ArticleDOI
Chemical characteristics of volcanic rocks: Relation to plate movements
TL;DR: The chemical compositions of Quaternary volcanic products which occur along the closing boundary of plates vary systematically with the closing rate of the plates as discussed by the authors, and it is probable that the amount of water provided to the wedge of the mantle from the descending plate controls the abundance of andesite, while the temperature distribution under volcanoes regulates the alkalinity of magmas.

Ce isotope ratios of N-type MORB
Akio Makishima,Akimasa Masuda +1 more
TL;DR: Isotope ratios of Ce, Nd and Sr, and light rare-earth elements (La, Ce, nd and Sm) concentrations were measured for sixteen N-type MORB samples from DSDP Sites 420, 421, 429, 597 B and 597 C (East Pacific Rise), 504 B (Costa Rica Rift), and 395, 519 A, 522 B, 562 and 564 (Mid Atlantic Ridge).

Arc-tholeiite and ultramafic cumulate, Brook Street Volcanics, west O'Urvilie Island, New Zealand
TL;DR: The Brook Street Volcanics at west D'Urville Island, New Zealand as mentioned in this paper show a trend of moderate iron enrichment and possess anomalously low Ti, Zr, and Nb abundances.

Volcanism associated with extension in an Oligocene—Miocene arc, southwestern Viti Levu, Fiji
TL;DR: The Wainimala Group rocks of southwestern Viti Levu, Fiji, represent part of an Oligocene-Miocene island arc as mentioned in this paper, and some of the early volcanism in this arc took place on a substrate of Eocene-Oligocene frontal-arc crust.

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.
