Water plays an important role in most processes within the Earth's mantle, eg transport
phenomena, differentiation and seismic properties. This paper reviews the various aspects …

We derive a novel method for determining the oxidation state of a magma as zircon
crystallized, with a standard error of±0· 6 log unit ƒO2, using ratios of Ce, U, and Ti in zircon …

Most of the intrusions in the Noril'sk-Talnakh region (Siberia) are hosted in thick sedimentary
sequences including abundant evaporitic and terrigenous sedimentary rocks. Three mafic …

Granitic—rhyolitic liquids were produced experimentally from moderately hydrous (1.7–2.3
wt% H 2 O) medium-to-high K basaltic compositions at 700 MPa and f O 2 controlled from Ni …

Experiments were conducted to study the temporal evolution of feldspar crystallization
kinetics during isothermal decompression. Pinatubo dacite was held at 780° C, 220 MPa …

This study focuses on the production of convergent margin calc-alkaline andesites by
crystallization–differentiation of basaltic magmas in the lower to middle crust. Previous …

The water-saturated phase relations have been determined for a primitive magnesian
andesite (57 wt% SiO 2, 9 wt% MgO) from the Mt. Shasta, CA region over the pressure range …

The lower mantle constitutes more than half the Earth's interior by volume, and is believed to
consist predominantly of (Mg, Fe) SiO3 perovskite with up to approximately 20%(Mg, Fe) O …

A series of high temperature experiments was undertaken to study partitioning of several
highly siderophile elements (HSE; Ru, Rh, Pd, Re, Os, Ir, Pt and Au) between Cr-rich spinel …

We performed new experiments on incorporation of hydrogen in olivine at high pressures (2–
12 GPa) and temperatures (1000–1300° C). OH concentrations were calculated using the …
