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

The modification of magma through mixing or through assimilation of country rocks is
commonly inferred from various chemical and isotopic features of magmatic rock suites and …

Differentiation of hydrous primary, mantle-derived magmas is a fundamental process to
generate evolved intermediate to SiO2-rich compositions forming the bulk of the continental …

Amphibole thermodynamics are approximated with the symmetric formalism (regular
solution model for within-site non-ideality and a reciprocal solution model for cross-site …

To evaluate the role of garnet and amphibole fractionation at conditions relevant for the
crystallization of magmas in the roots of island arcs, a series of experiments were performed …

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 …

Andesites represent a large proportion of the magmas erupted at continental arc volcanoes
and are regarded as a major component in the formation of continental crust. Andesite …

Mesozoic intermediate–felsic intrusions are widely distributed in the southern Qiangtang
terrane, central Tibet. Zircon U–Pb dating shows that these intrusions formed in two periods …

Trace-element abundances were measured in situ by ion microprobe in five samples of
hornblende and melt ranging from basaltic andesite to high-silica rhyolite. Except for one …

Experimental evidence is used to estimate H 2 O contents in low-MgO high-alumina basalts
(HABs)(< 6 wt.% MgO) and basaltic andesites (BAs)(< 5 wt.% MgO) that occur worldwide in …
