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:

Primitive island arc and oceanic lavas from the hunter ridge-hunter fracture zone. Evidence from glass, olivine and spinel compositions
I. A. Sigurdsson,Vadim S. Kamenetsky,Vadim S. Kamenetsky,Anthony J. Crawford,Stephen Eggins,Sergei K. Zlobin +5 more
TL;DR: In this article, the authors define nine magmatic groups from major element glass chemistry and olivine and spinel compositions in samples dredged from twenty six sites in this area by the "R/V Academician A. Nesmeyanov'' in 1990.

Trace elements and Nd-Sr isotopes of island arc tholeiites from frontal arc of Northeast Japan
Shigeko Togashi,Tsuyoshi Tanaka,Takeyoshi Yoshida,Ken-ichi Ishikawa,Akihiko Fujinawa,Hajime Kurasawa +5 more
TL;DR: In this article, it is argued that U-IAT magmas were derived by 5-10% batch partial melting of the primitive mantle. But, these variations can be explained by a variation in the composition of a previously depleted mantle source.

Crystallization of garnet-bearing rhyodacite under high-pressure hydrous conditions
Trevor H. Green,A.E. Ringwood +1 more
TL;DR: In this article, a high-pressure, high-temperature investigation of a glass prepared from a natural garnet-bearing rhyodacite from Victoria has been conducted under anhydrous and hydrous conditions (2, 5 and 10% by weight of water added).

Evolution of the South Philippine Sea: Deep Sea Drilling Project Leg 59 Results
TL;DR: Karig et al. as mentioned in this paper proposed two hypotheses for the origin of the marginal basins of the South Philippine Sea: the entrapment of preexisting oceanic crust and the formation of new seafloor spreading by back-arc sea floor spreading.

Petrology of the Tekirova (Antalya) ophiolite (Southern Turkey): evidence for diverse magma generations and their tectonic implications during Neotethyan-subduction
TL;DR: In this article, the isolated dikes and isotropic gabbros of the Tekirova (Antalya) ophiolite have been used to identify parent basic magmas that formed the oceanic crustal rocks.

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.
