Geochemical discrimination of different magma series and their differentiation products using immobile elements
TL;DR: In this article, the abundance and distribution of selected minor and trace elements (Ti, Zr, Y, Nb, Ce, Ga and Sc) in fresh volcanic rocks can be used to classify the differentiation products of subalkaline and alkaline magma series in a similar manner to methods using normative or major-element indices.
Journal ArticleDOI
Ti-V plots and the petrogenesis of modern and ophiolitic lavas
TL;DR: In this article, the authors applied the Ti/V plot to published data on ophiolites from a variety of postulated settings and in general supported the conclusions of previous investigators.
Journal ArticleDOI
An evaluation of the global variations in the major element chemistry of arc basalts
Terry Plank,Charles H. Langmuir +1 more
TL;DR: In this paper, the authors show that the extent of melting in the mantle can easily account for the associated variations in Ca6.0 and Na6. 0 in the parent magmas.
Journal ArticleDOI
Relations of andesites, granites, and derivative sandstones to arc‐Trench tectonics
TL;DR: In this paper, the authors present a model for the origin of andesitic and granitic batholiths, which is based on the assumption that the plutons were formed in the roots of complex volcanoplutonic arcs, and that granitic intrusive magmas may be derived from the same deep sources as andeitic eruptive magmas.

Examination of the deep levels of an island arc: Evidence from the Tonsina Ultramafic‐Mafic Assemblage, Tonsina, Alaska
TL;DR: The Tonsina ultramafic and mafic assemblage is interpreted to be the remains of a magma chamber that crystallized at the base of a mature interoceanic island arc as mentioned in this paper.

Role of oxygen pressure in the crystallization and differentiation of basaltic magma
TL;DR: In this paper, two types of crystallization paths in iron oxide systems are illustrated by describing equilibrium crystallization in the fayalite field of the system FeO-Fe 2 O 3 -SiO 2.

The geochemistry of some igneous rock series
S. R. Nockolds,R. Allen +1 more
TL;DR: In this paper, the distribution of some of the commoner trace elements with respect to the major elements in various igneous rock series is discussed. But the present communication deals with certain calc-alkali igneous rocks series, namely, the rocks of the Southern California batholith, the lavas of Lassen Peak, Crater Lake, the Lesser Antilles, the Medicine Lake Highlands and the East Central Sierra Nevada.
Journal ArticleDOI
Origin of cenozoic petrographic provinces of Japan and surrounding areas
TL;DR: The boundary lines between the tholeiite and alkali petrographic provinces are located very closely to those between the areas where earthquakes occur at depths shallower than about 200 km and those for deeper ones as mentioned in this paper.
Journal ArticleDOI
Primary magmas and the origin of basalts
TL;DR: In this article, it has been shown that extrusive basaltic rocks have chemical compositions and behave under experimental conditions in a way which suggests that they are, in the main, the residual liquids of well advanced crystal fractionation processes operating at relatively low pressures.
