Field, geochronological and geophysical studies show that many igneous bodies are
emplaced incrementally, growing by accretion of successive magma sheets. The existence …

Silicic magmas play an important role in the formation of continental crust and are
responsible for some of the most hazardous volcanic eruptions on the planet. Low-δ 18 O …

This textbook is a complete rewrite, and expansion of Hugh Rollinson's highly successful
1993 book Using Geochemical Data: Evaluation, Presentation, Interpretation. Rollinson and …

Two geochemical proxies are particularly important for the identification and classification of
oceanic basalts: the Th–Nb proxy for crustal input and hence for demonstrating an oceanic …

A model for the generation of intermediate and silicic igneous rocks is presented, based on
experimental data and numerical modelling. The model is directed at subduction-related …

A one-dimensional thermal conduction model simulates the repetitive intrusion of basalt sills
into the deeper parts of the crust. The model assumes geothermal gradients of 10–30° C …

Evolved magmas, including highly explosive rhyolites, are mainly generated by extraction of
viscous melts from solid residues either in (1) partial melting zones within the crust …

Post-collisional (26.2 to 10.1 Ma) adakites occur within the Lhasa terrane of the southern
Tibetan Plateau in an E–W trending, 1500 km long, magmatic belt. Outcrops are small and …

Geochemical data for igneous rocks provide definitive evidence for the occurrence of open-
system processes in magma bodies, including Replenishment by intrusion of primitive …

We report major and trace element abundances for 147 samples and Sr, Nd, Hf, and Pb
isotope compositions for a 36 sample subset of basaltic lava flows, sills, and dykes from the …
