Adakite petrogenesis
Adakite was originally proposed as a genetic term to define intermediate to high-silica, high

Making continental crust
The continental crust has an andesitic bulk composition, which cannot have been produced
by the basaltic magmatism that dominates sites of present-day crustal growth—at both …

Element transport from slab to volcanic front at the Mariana arc
We present a comprehensive geochemical data set for the most recent volcanics from the
Mariana Islands, which provides new constraints on the timing and nature of fluxes from the …

Adakites without slab melting: high pressure differentiation of island arc magma, Mindanao, the Philippines
New geochemical data for Pleistocene magmatic rocks from the Surigao peninsula, eastern
Mindanao, the Philippines, demonstrate typical adakitic traits, including elevation of Sr/Y and …

Geochemical evidence for mélange melting in global arcs
In subduction zones, sediments and hydrothermally altered oceanic crust, which together
form part of the subducting slab, contribute to the chemical composition of lavas erupted at …

Sampling mantle heterogeneity through oceanic basalts: isotopes and trace elements
AW Hofmann, RW Carlson - 2003 - books.google.com
Thus, Hurley and his collaborators were able to distinguish crustal magma sources from
those located in the mantle on the basis of their initial strontium-isotopic compositions …

Oxygen isotope variations of basaltic lavas and upper mantle rocks
This chapter summarizes the oxygen isotope geochemistry of terrestrial basalts and their
mantle sources, including the conceptual framework for interpreting such data and the …

FOZO, HIMU, and the rest of the mantle zoo
The parameter μ describes the 238U/204Pb ratio of an Earth reservoir. Mantle domains

Uranium isotope fractionation
This review focuses on the rapidly growing field of natural 238U/235U variability, largely
driven by the technical advances in the measurement of U isotope ratios by mass …
