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:

Trace-element zoning in garnets from sheared mantle xenoliths
TL;DR: Proton-microprobe analyses of garnets from sheared high-temperature ultramafic xenoliths reveal marked zonation of trace elements, paralleling trends in major and minor elements as mentioned in this paper.
Journal ArticleDOI
Petrochemistry and tectonic significance of Dalradian metabasaltic rocks of the SW. Scottish Highlands
TL;DR: In this paper, an altered, soda-rich group of spilitic affinity, often accompanied by epidotic segregations, is readily distinguished from unaltered basaltic compositions using chemical and modal criteria.

Geochemical discrimination of metabasalt rocks of the Fan Karategin transitional blueschist/greenschist belt, South Tianshan, Tajikistan: seamount volcanism and accretionary tectonics
N.I Volkova,V.I Budanov +1 more
TL;DR: The Fan-Karategin metamorphic belt, South Tianshan, Tajikistan, is regarded to be an ancient subduction-accretionary complex and is composed of three tectonostratigraphic units which display lithologies consistent with different tectonic settings.

Multi-Stage Origin of the Coast Range Ophiolite, California: Implications for the Life Cycle of Supra-Subduction Zone Ophiolites
John W. Shervais,David L. Kimbrough,Paul R. Renne,Barry B. Hanan,Benita L. Murchey,Cameron A. Snow,Marchell M. Zoglman Schuman,Joe Beaman +7 more
TL;DR: The Coast Range ophiolite of California is one of the most extensive ophiliite terranes in North America, extending over 700 km from the northernmost Sacramento Valley to the southern Transverse Ranges in central California as discussed by the authors.
Journal ArticleDOI
Trace-element geochemistry of archean greenstone belts
TL;DR: Agarwal et al. as mentioned in this paper investigated the trace-element distribution in Archean greenstone greenstone belts and found that most of the trace element distributions in greenstone volcanic rocks are enriched in transition metals compared to modern varieties.

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
P. Jakeš,A. J. R. White +1 more
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.
