Documenting multiple metasomatic events within the Finero phlogopite peridotite using chlorine isotopes, Ivrea zone, Italy
Depleted mantle peridotites from the Finero body in the Ivrea Zone were infiltrated by metasomatizing melts/fluids prior to their incorporation into the lower continental crust. Metasomatism resulted in pervasive development of phlogopite and amphibole throughout much of the body, as well as the …

Petrology and geochemistry of Sangeang Api and recent volcanism in the Sumbawa-Flores sector of the Sunda Arc: the response of along-arc geochemistry to subduction processes.
… a role for residual amphibole in the mantle source. Wai Sano at the far western end of Flores, is unique in the Sunda Arc, erupting adakites with characteristically low MgO, high Al₂O₃, high SiO₂, low Y and high Sr/Y. However, the Sr-Nd isotope systematics of these lavas suggests that …

Halogens and trace elements in subduction zones
… The solubility of fluorine and chlorine in upper mantle minerals (forsterite, enstatite and pyrope) and halogen partitioning between aqueous fluids and these minerals were investigated by piston-cylinder experiments at 1100 °C and 2.6 GPa. Chlorine solubility in forsterite, enstatite and pyrope is …

The isotope geochemistry of abyssal peridotites and related rocks
… aspects of the formation of the Earth's oceanic mantle and crust, using a variety of geologic techniques, principally major elements, radiogenic isotopes and trace elements, but including petrography, mineral chemistry, x-ray diffraction, seafloor geomorphology, and analysis of the tectonics of …
