Thermal Stability of F‐Rich Phlogopite and K‐Richterite During Partial Melting of Metasomatized Mantle Peridotite With Implications for Deep Earth Volatile Cycles Open
Phlogopite and K‐richterite constitute important carrier phases for H and F in Earth's lithosphere and mantle. The relative importance depends on their stabilities at high pressure and temperature, which in turn depends on bulk composition…

Titanium-rich basaltic melts on the Moon modulated by reactive flow processes Open
The origin of titanium-rich basaltic magmatism on the Moon remains enigmatic. Ilmenite-bearing cumulates in the lunar mantle are often credited as the source, but their partial melts are not a compositional match and are too dense to enabl…

High-precision, mass dependent Si isotope measurements <i>via</i> the critical mixture double-spiking technique Open
We developed critical mixture double-spiking Si isotope measurement, achieving an enhanced long-term reproducibility of ±0.03‰ ( δ 30 Si, 2 s.d.), which is ∼4 times better than the current methods' long-term reproducibility over ±0.1‰ ( δ …

Widespread slab melting in modern subduction zones Open
It is still a matter of intense debate to what extent partial melting of the subducting slab contributes to arc magmatism in modern subduction zones. In particular, it is difficult to differentiate between silicate melts formed by partial …

Calcium Isotope Evolution During Differentiation of Vesta and Calcium Isotopic Heterogeneities in the Inner Solar System Open
We employed MC‐ICP‐MS to measure the mass‐dependent Ca isotope compositions of Vesta‐related meteorites. Eucrites and diogenites show distinct Ca isotope compositions, which is caused by crystallization of isotopically heavy orthopyroxene.…

Deep to Shallow Sulfide Saturation at Nisyros Active Volcano Open
We report new petrographic and geochemical observations on magmatic sulfides occurring in different enclave types, including hornblende and/or clinopyroxene‐rich cumulates, and in the host lavas, in Nisyros (South Aegean volcanic arc). We …

The effects of hydrodynamic sorting on the Ti isotope composition of sediments Open
<p>Detrital sediments provide a useful tool to investigate the composition of the continental crust through time. Mass-dependent (&#8220;stable&#8221;) isotope variations in Archaean to present-day sediments (shales, diamicti…

Optimised techniques to determine coupled trace element and Sr-Nd-Pb isotope ratios in olivine-hosted melt inclusions Open
Melt inclusions (MIs) in deeply formed magmatic minerals are typically characterised by larger variability in major and trace element- and isotope compositions compared to bulk lavas. The larger geochemical variability reflects that MIs re…

Evidence for a Moist to Wet Source Transition Throughout the Oman‐UAE Ophiolite, and Implications for the Geodynamic History Open
The Oman‐United Arab Emirates (UAE) ophiolite represents the largest and best‐preserved fragment of obducted oceanic lithosphere in the world. However, debate continues regarding its geodynamic history. This debate is in part a consequence…

Obtaining Accurate Isotopic Compositions with the Double Spike Technique: Practical Considerations Open
Ever‐increasing precision in isotope ratio measurements requires a concomitant small bias within and between laboratories. The double spike technique is the most suitable method to obtain reliable isotope composition data that are accurate…

Isotopic variation in Semail Ophiolite lower crust reveals crustal-level melt aggregation Open
The scale and magnitude of compositional heterogeneity in the mantle has important implications for the understanding of the evolution of Earth. Heterogeneity of the upper mantle is often evaluated based on mid-ocean ridge basalt compositi…

A distinct source and differentiation history for Kolumbo submarine volcano, Santorini volcanic field, Aegean arc Open
This study reports the first detailed geochemical characterization of Kolumbo submarine volcano in order to investigate the role of source heterogeneity in controlling geochemical variability within the Santorini volcanic field in the cent…
