The relationship between major element chemistry and tectonic environment of basic and intermediate volcanic rocks
TLDR
In this paper, a ternary plot of MgO FeO(total) Al2O3 was used to distinguish five tectonic environments: ocean ridge and floor, ocean island, continental, orogenic, and spreading center island.About:

MnO/TiO2/P2O5: a minor element discriminant for basaltic rocks of oceanic environments and its implications for petrogenesis
TL;DR: A ternary diagram using MnO, TiO 2, P 2 O 5 can discriminate between five petrotectonic environments of basaltic rocks (45-54% SiO 2 ).

Paleozoic tectonic evolution of the Tianshan Orogen, northwestern China
TL;DR: The Chinese Tianshan orogenic belt as discussed by the authors extends west-east for about 1500 km and includes parts of the Tarim, Yili-Central Tianhan and Junggar plates, which are microcontinental blocks with Precambrian basements.

A 1.78 Ga large igneous province in the North China craton: The Xiong'er volcanic province and the North China dyke Swarm
TL;DR: The 1.78 Ga Xiong'er Volcanic Province (XVP) and coeval North China giant mafic Dyke Swarm (NCDS) are the most important magmatic events occurring after the amalgamation of the North China craton (NCC) as discussed by the authors.
Journal ArticleDOI
How deep do common basaltic magmas form and differentiate
TL;DR: In this paper, the authors investigated the potential of experiments on peridotite melting to provide quantitative estimates of the temperature and pressure at which basaltic melts were formed, and the chemical compositions of synthetic melts were fitted not as a function of the degree of melting, which is neither available from the sandwich experiments nor independent of the fertility of the source.

The geochemical fingerprints of different tectonomagmatic environments using hygromagmatophile element abundances of tholeiitic basalts and basaltic andesites
TL;DR: Using hygromagmatophile element abundances (normalized to primordial mantle composition), it is possible to discriminate between the tectonic settings of tholeiitic basalts and basaltic andesites (47.0-53.5% SiO2) as discussed by the authors.

Tectonic setting of basic volcanic rocks determined using trace element analyses
Julian A. Pearce,J.R. Cann +1 more
TL;DR: 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.

Magma type and tectonic setting discrimination using immobile elements
TL;DR: In this paper, five minor and trace elements have been variously combined to produce a set of binary diagrams in addition to total alkali-SiO2 diagrams, that discriminate between fresh tholeiitic and alkali basalts.

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.

Sea floor basalt alteration: Some chemical and Sr isotopic effects
TL;DR: In this article, the major element, Sr isotope and trace element data for 16 elements are reported for various weathered zones in three submarine basalt pillows, and it appears that SiO2, Al2O3, CaO, S, and Ga are lost from the basalt during the initial stages of alteration.
