TLDR
In this paper, the results of analyses for Ti, Zr, Y, Nb and Sr in over 200 basaltic rocks from different tectonic settings have been used to construct diagrams in which these settings can usually be identified.About:

Permo-Carboniferous magmatism of the Northeast German Basin
R. Benek,W. Kramer,Tom McCann,M. Scheck,Jörg F. W. Negendank,D. Korich,H.-D. Huebscher,U. Bayer +7 more
TL;DR: In this paper, a total of five eruptive stages are recognized beginning in the Stephanian and extending up into the Upper Rotliegend (Permian) age late basalt stage.

Field and geochemical data bearing on the development of a mesozoic volcano-tectonic rift zone and back-arc basin in southernmost South America
TL;DR: A broad zone of dominantly subaerial silicicic volcanism associated with regional extensional faulting developed in southern South America during the Middle Jurassic, contemporaneously with the initiation of plutonism along the present Pacific continental margin this article.

Trace element indiscrimination diagrams
TL;DR: In this paper, the accuracy of trace element discrimination diagrams for basalts using new datasets from two petrological databases, PetDB and GEOROC, was tested using both binary and ternary diagrams using Zr, Ti, V, Y, Th, Hf, Nb, Ta, Sm, and Sc.

Geochemistry of basaltic and gabbroic rocks from the West Mariana basin and the Mariana trench
TL;DR: In this article, the chemistry of 33 basaltic rocks dredged from the West Mariana basin and from the Mariana trench during the R/V “Dmitry Mendeleev” 1976 cruise in the western Pacific is described.

Geochemistry of quaternary volcanism in the Sunda-Banda arc, Indonesia, and three-component genesis of island-arc basaltic magmas
TL;DR: The Sunda-Banda arc is divided into four geochemical arc sectors with boundaries that correlate with major changes in regional tectonic setting and geological history as mentioned in this paper, and the most marked geochemical and isotopic variations shown by the arc volcanics are primarily due to the involvement of a third component, which is rich in K-group elements but has relatively low 87 Sr/86 Sr values.

Origin and development of marginal basins in the western Pacific
TL;DR: In this paper, the existence of low density, high temperature upper mantle is indicated by the lack of a large gravity anomaly over the shallow oceanic crust of the inter-arc basin, by high heat flow there, and by anomalously high attenuation of shear waves passing through the upper mantle beneath the extensional zone.

The Troodos Massif, Cyprus and other Ophiolites as Oceanic Crust: Evaluation and Implications
Eldridge M. Moores,F. J. Vine +1 more
TL;DR: The Troodos Massif as discussed by the authors consists of a pseudostratiform mass of harzburgite, dunite, pyroxenite, gabbro, quartz diorite, diabase and pillow lava arranged in a dome-like manner.

Major and Trace Element Abundances in Volcanic Rocks of Orogenic Areas

TL;DR: In this paper, the composition of island-arc volcanic rocks in relation to their geographic and stratigraphic relations is discussed and the differences in composition between volcanic rocks and those in continental margins are pointed out.

Rare earth elements and the island arc tholeiitic series
P. Jakesˇ,James B. Gill +1 more
TL;DR: 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.
