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:

Shoshonitic volcanism in the Northern Mariana Arc: 1. Mineralogic and major and trace element characteristics
TL;DR: Petrographic and geochemical characteristics of samples dredged from 23 submarine volcanic edifices in the northern Mariana and southern Volcano arcs define two distinct rock series as mentioned in this paper, including both low-K and medium-K series.

Geochemistry of basalts from central and southern New Hebrides arc: implication for their source rock composition
TL;DR: The basaltic rocks from the central and southern islands of the New Hebrides-Aneityum, Tanna, Erromango, Efate, Emae, Tongoa and Epi, have geochemical features typical of island arc volcanics.

Melting relations of muscovite-granite to 35 kbar as a model for fusion of metamorphosed subducted oceanic sediments
W. L. Huang,Peter J. Wyllie +1 more
TL;DR: In this paper, the phase relationship of a muscovite-granite reaction with excess water was presented through the melting interval with no free water added, and with an isobar at 15 kbar showing the effect of varying water contents on the mineral phase boundaries.

The subduction factory : its role in the evolution of the Earth's crust and mantle
Yoshiyuki Tatsumi,Tetsu Kogiso +1 more
TL;DR: In this paper, the authors examined geochemical characteristics of calcalkalic andesites in the NE Japan arc and bulk continental crust and revealed compositional similarity between calc-alkalistic andesite and continental crust.

Ancient and modern volcanic rocks: A trace element model
TL;DR: In terms of the relative abundance of K, Rb, Cs, Sr and Ba, modern oceanic and island-arc basalts may be viewed as a gradational family ranging from alkali basalt (enriched in these elements) to low-K-tholeiite, such as ocean-floor basalt as mentioned in this paper.

Distribution of the Elements in Some Major Units of the Earth's Crust
Karl K. Turekian,K. H. Wedepohl +1 more

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.

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.
