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:

Chemistry of the subalkalic silicic obsidians
TL;DR: In this paper, the authors present a data bank of subalkalic silicic obsidians and describe the characteristics of the obsidian subgroups and their relationships among A1 2O3, CaO, and (NajO+K^O).

Oxygen isotopic compositions of volcanic rocks from the east Japan island arcs and their bearing on petrogenesis
TL;DR: In this article, the authors measured 118 volcanic rocks and coexisting minerals and groundmass from the East Japan island arcs and found that the whole-rock σ 18 O values relative to SMOW range from +4.45 to +7.80 and show a tendency for 18 O enrichment with increasing SiO 2 content.

Genesis of Mariana shoshonites: Contribution of the subduction component
Chih Hsien Sun,Robert J. Stern +1 more
TL;DR: The Izu-Bonin-Mariana arc contains a unique group of shoshonitic volcanoes from along the magmatic front of this intraoceanic arc as mentioned in this paper.

Geochemistry of arc volcanic rocks of the Zagros Crush Zone, Neyriz, Iran
TL;DR: In this article, the authors describe the petrographic and geochemical characteristics of the Hassanabad Unit of the Tethyan Neyriz ophiolite complex in southwestern Iran, which is tectonically juxtaposed under cataclastically-deformed island arc volcanic-volcaniclastic rocks.

Tillamook Volcanic Series: Further evidence for tectonic rotation of the Oregon Coast Range
TL;DR: In this paper, a two phase model was developed to explain the tectonic history and anomalous magnetic field directions of the Pacific northwest region, and the authors established that the Oregon coastal block of Simpson and Cox (1977) extends north to the Oregon-Washington border and that this block has rotated clockwise 46 o + 13 o during the past 44 m.y.b.

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.

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.
