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:

Subduction of pelagic sediments: implications for the origin of Ce-anomalous basalts from the Mariana Islands
TL;DR: In this paper, a series of pelagic clays and nannofossil oozes from the Nazca Plate were analyzed for trace element and other trace elements, and the authors attempted to model the contribution of PAWMS-type material to the source of the magmas of the Mariana Island Arc, an intra-oceanic arc far removed from the effect of continent-derived detritus.

Iron oxide-copper-gold deposits: an Andean view
TL;DR: In this paper, a genetic connection of the central Andean IOCG deposits with gabbrodiorite to diorite magmas from which the ore fluid may have been channelled by major ductile to brittle fault systems for several kilometres vertically or perhaps even laterally.

The Lesser Antilles volcanic chain : a study in arc magmatism.
TL;DR: In this article, the authors investigated the influence of the sediment component relative to that of hydrous fluids generally increases towards the south of the Lesser Antilles volcanic arc and found that the proportions of each component in the different magma types are still debated, as is the importance of crustal contamination in producing their trace element and isotopic characteristics.

Magma Genesis in the New Britain Island Arc: Further Insights into Melting and Mass Transfer Processes
TL;DR: In this paper, the authors proposed that the high field strength elements of the processes of magma genesis in an oceanic island (HFSE) are extremely depleted in the volcanic front rocks compared arc.

A Review of the Mineralogy and Chemistry of Tertiary-Recent Dacitic, Latitic, Rhyolitic, and Related Salic Volcanic Rocks
TL;DR: In this paper, a compilation of major and trace elements, plus phenocryst occurrence and phenotypic modal data are used to classify salic volcanic eruptions into five chemical groups (60-63, 63-66, 66-69, 69-72, and >73% SiO2), and further chemical subdivision into low-K, calcalkaline, and high-K series from each subregion.

Karl K. Turekian,K. H. Wedepohl +1 more

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.

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.
