Trace element discrimination diagrams for the tectonic interpretation of granitic rocks
TL;DR: In this article, a data bank containing over 600 high quality trace element analyses of granites from known settings was used to demonstrate using ORG-normalized geochemical patterns and element-SiO2 plots that most of these granite groups exhibit distinctive trace element characteristics.

Tectonic discrimination of granitoids
Papu D. Maniar,Philip M. Piccoli +1 more
TL;DR: In this paper, the classification of granitoids is based on the major-element chemistry, and various discrimination plots are presented which sequentially discriminate the different tectonic environments.

Adakitic magmas: modern analogues of Archaean granitoids
TL;DR: Sajona et al. as mentioned in this paper showed that the liquids produced by melting of tholeiite in subduction-like P-T conditions are adakitic in composition, indicating that modern adakites have trondhjemitic affinities (high Na2O contents and K2O/Na2O∼0.5) and their Mg no.
Journal ArticleDOI
A review of the relationships between granitoid types, their origins and their geodynamic environments
TL;DR: Granitoids are divided into several types according to their mineral assemblages, their field and petrographical features, and their chemical and isotopic characteristics.
Journal ArticleDOI
Voluminous granitic magmas from common basaltic sources
TL;DR: Granitic-rhyolitic liquids were produced experimentally from moderately hydrous (1.7-2.3% H2O) medium-to-high K basaltic compositions at 700 MPa and fO2 controlled from Ni-NiO −1.3 to +4.5% as mentioned in this paper.

Average chemical compositions of some igneous rocks
TL;DR: In this paper, the average chemical compositions for the common plutonic rock types and their volcanic equivalents are given for the general average chemical composition of silicic, intermediate, subsilicic and ultramafic igneous rocks.
