The Lesser Antilles volcanic arc is related to subduction of the American plate under the
Caribbean plate. The rate of subduction is low, 2–4 cm a− 1, and this has been reflected, at …

We review data and recent research on arc composition, focusing on the relatively complete
arc crustal sections in the Jurassic Talkeetna arc (south central Alaska) and the Cretaceous …

Phase relations of natural aphyric high-alumina basalts and their intrusive equivalents were
determined through rock-melting experiments at 2 kb, H 2 O-saturated with f O 2 buffered at …

The origin of different kinds of granitic rocks is examined within the framework of
experimental studies of melting of metamorphic rocks, and of reaction between basaltic …

The phase relations of primitive magnesian andesites and basaltic andesites from the Mt.
Shasta region, N California have been determined over a range of pressure and …

Exposed, subduction-related magmatic arcs commonly include sections of ultramafic
plutonic rocks that are composed of dunite, wehrlite, and pyroxenite. In this experimental …

Equilibrium crystallization experiments at atmospheric pressure and over a range of oxygen
fugacity (f O2) have been carried out on a ferro-basaltic composition similar to liquids …

Most variations in composition among primitive basalts from the Mariana back-arc trough
can be explained by melting mixtures of an NMORB-type mantle source and an H 2 O-rich …

Examination of an extensive major and trace element database for about 700 whole rocks
from the Ecuadorian Andes reveals series of local trends typified by three volcanoes: Iliniza …

This paper reports experiments carried out between 1.5 and 2.3 GPa using synthetic
analogs of the molten peridotite system to investigate the effects of pressure (P), temperature …
