Oblique aseismic subduction below western Panama and southeastern Costa Rica has
produced Recent arc-related volcanism. The aseismicity is probably related to the …

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 …

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 continental crust has an andesitic composition with high Mg/(Mg+ Fe) and Ni contents
which may be too high to have formed by differentiation of basaltic magmas. Instead, mantle …

We present a detailed, new time scale for an orogenic cycle (oceanic accretion–subduction–
collision) that provides significant insights into Paleozoic continental growth processes in the …

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 …

The Pliocene—Pleistocene magmatic activity of the Zamboanga are is linked to the
southward subduction of the Oligocene—Mio-cene Sulu Sea back-are basin along the Sulu …

This paper presents results of modelling reaction between peridotite and fractionating
tholeiitic basalt in simple and complex silicate systems. Reactions are outlined in …

Arc volcanoes occur at convergent margins with a wide range in subduction parameters,
and variations in these parameters might be expected to lead to variations in the chemistry …

The origin of tholeiitic (TH) versus calc-alkaline (CA) magmatic trends has long been
debated. Part of the problem stems from the lack of a quantitative measure for the way in …
