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:

Tectonic Setting, Origin, and Obduction History of the Spontang Ophiolite, Ladakh Himalaya, NW India
TL;DR: The Spontang ophiolite formed at a normal mid-ocean ridge spanned by the Mesozoic-Early Tertiary continental margin of the north Indian plate in the Ladakh-Zanskar Himalaya.
Journal ArticleDOI
Petrology, geochemistry and tectonics of the Sabzevar ophiolite, North Central Iran
TL;DR: The Sabzevar ophiolite is a highly dismembered ophiorite complex located along the northern boundary of the central Iranian microcontinent (CIM), and is one of the internal Iranian group of Ophiolites and colored melanges as discussed by the authors.
Journal ArticleDOI
Petrology, geochemistry, and geochronology of the Zhonggang ocean island, northern Tibet: implications for the evolution of the Banggongco–Nujiang oceanic arm of the Neo-Tethys
TL;DR: In this paper, the authors presented new data relating to the tectonic evolution of the Zhonggang ocean island, within the Mesozoic Banggongco-Nujiang suture zone of northern Tibet, and discussed the implications of these data for the evolution of this region.
Journal ArticleDOI
The Central Ailaoshan ophiolite and modern analogs
Chun-Kit Lai,Sebastien Meffre,Anthony J. Crawford,Khin Zaw,Jacqueline A. Halpin,Chuan-Dong Xue,Abhisit Salam +6 more
TL;DR: The Central Ailaoshan (CAL) ophiolite represents an important tectonic component of the Jinshajiang-Ailaoshans-Song Ma suture zone separating the South China and Indochina blocks in the mainland SE Asia as discussed by the authors.
Journal ArticleDOI
Development of concepts concerning the Troodos ophiolite and adjacent units in Cyprus
TL;DR: In the early 1970s, the dominant view of the Troodos was of a mid-ocean ridge, formed by spreading at a narrow, linear spreading zone, fed by a single, axial magma chamber as discussed by the authors.

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.
