Li–Na interdiffusion and diffusion-driven lithium isotope fractionation in pegmatitic melts [PDF]
European Journal of Mineralogy, 2023 In this study, we investigate the diffusion of Li and its stable isotopes (6Li and 7Li) in flux-rich (1.8 % Li2O, 2.6 % B2O3, 2.3 % P2O5 and 3 % F) pegmatitic melts in order to contribute to the understanding of Li enrichment in such systems. Two glasses

Depth profile analyses by femtosecond laser ablation (multicollector) inductively coupled plasma mass spectrometry for resolving chemical and isotopic gradients in minerals [PDF]
European Journal of Mineralogy, 2023 Femtosecond laser ablation (fs-LA) coupled to a multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS) instrument has been proven to be a powerful means to analyze isotope ratios of “non-traditional” stable isotope systems with high ...

CO2 diffusion in dry and hydrous leucititic melt [PDF]
European Journal of Mineralogy, 2023 Using the diffusion couple technique, diffusion of CO2 in a leucititic melt from the Colli Albani Volcanic District in Italy was investigated at temperatures between 1200 and 1350 ∘C in an internally heated pressure vessel at 300 MPa.

Teleseismic P waves at the AlpArray seismic network: wave fronts, absolute travel times and travel-time residuals [PDF]
Solid Earth, 2021 We present an extensive dataset of highly accurate absolute travel times and travel-time residuals of teleseismic P waves recorded by the AlpArray Seismic Network and complementary field experiments in the years from 2015 to 2019. The dataset is intended

Chemical Geodynamics Insights From a Machine Learning Approach
Geochemistry, Geophysics, Geosystems, 2022 The radiogenic isotope heterogeneity of oceanic basalts is often assessed using 2D isotope ratio diagrams. But because the underlying data are at least six dimensional (87Sr/86Sr, 143Nd/144Nd, 176Hf/177Hf, and 208,207,206Pb/204Pb), it is important to ...

Mixing between chemically variable primitive basalts creates and modifies crystal cargoes
Nature Communications, 2021 Chemically variable primitive basalts undergo mixing during ascent from the mantle. Here the authors show observations from magma–magma reaction experiments which demonstrate how isothermal mixing between chemically variable basalts creates and modifies ...
