An assessment of the relative roles of crust and mantle in magma genesis: an elemental approach
TL;DR: In this paper, the elemental compositions of terrestrial igneous rocks are reviewed with special emphasis on those elements that partition strongly into the liquids in mafic and ultramafic systems.
Journal ArticleDOI
Elemental mobility during zeolite facies metamorphism of the Tertiary basalts of eastern Iceland
TL;DR: In this paper, major and trace element analyses are reported for 70 lavas from the Tertiary succession of eastern Iceland and the low grade regional metamorphism responsible for the zeolite zones appears to have caused significant mobilization of some elements, particularly Si, Mg, K, Rb, Sr and light rare earth elements.
Journal ArticleDOI
Primary basalts and magma genesis
TL;DR: In this article, three Eocene lavas from Skye, NW Scotland, have been subjected to anhydrous experimental studies within their melting ranges at pressures up to 30 kb, and two of these, an olivine-phyric magnesian alkali basalt and a nearaphyric Mg-poor transitional basalt, appear to show four-phase points on their liquidi at high pressures.
Journal ArticleDOI
Elemental fingerprints of isotopic contamination of hebridean Palaeocene mantle-derived magmas by archaean sial
TL;DR: In this article, it was shown that the major and trace-element compositions of the Skye and Mull plateau lavas of N.W. Scotland are variably isotopically contaminated by the Archaean Lewisian continental crust.
Journal ArticleDOI
Subduction-related shoshonitic and ultrapotassic magmatism; a study of Siluro-Ordovician syenites from the Scottish Caledonides
R. N. Thompson,M. B. Fowler +1 more
TL;DR: The Scottish Caledonian syenites are important or predominant components of several plutonic complexes, emplaced between 456 and 415 Ma along the NW margin of the caledonian orogenic belt, adjacent to the Lewisian foreland, in W and NW Scotland as discussed by the authors.
