Multi-Stage Magma Evolution in Intra-Plate Volcanoes: Insights From Combined in situ Li and Mg–Fe Chemical and Isotopic Diffusion Profiles in Olivine
Autor: Lena K. Steinmann, Martin Oeser, Ingo Horn, Stefan Weyer
Publikováno v: Frontiers in Earth Science, Vol 8 (2020)
Understanding the timescales of magma evolution and ascent is essential for interpreting geophysical monitoring signals from active volcanoes. In this study, we explore the potential of diffusion-driven Li concentration and isotope zoning profiles re

In situ high-precision lithium isotope analyses at low concentration levels with femtosecond-LA-MC-ICP-MS
Autor: Stefan Weyer, Hans-Michael Seitz, Ingo Horn, Lena K. Steinmann, Martin Oeser
Publikováno v: Journal of Analytical Atomic Spectrometry. 34:1447-1458
In this study we have established a new method for in situ measurements of stable lithium (Li) isotope ratios at low Li concentration levels using UV-femtosecond laser ablation coupled with multiple collector inductively coupled plasma mass spectrome

Most explosive, silicic volcanoes spend thousands of years in repose between eruptive events. The timing of the switch from repose to eruption is key to interpreting monitoring signals and improving the safety of people living close to active volcano

Experimental calibration and implications of olivine-melt vanadium oxybarometry for hydrous basaltic arc magmas
Autor: Francois Holtz, Dieter Garbe-Schönberg, Martin Oeser, T. A. Shishkina, Renat R. Almeev, Maxim Portnyagin, Stephan Schuth, Anna V. Simonyan, Roman E. Botcharnikov
Publikováno v: American Mineralogist. 103:369-383
The strong dependence of vanadium partitioning between olivine and silicate melt (DVOl-M) on redox conditions (fO2) can be used as sensitive oxybarometer in magmatic systems. Here we extend the experimental database on DVOl-M, obtained so far at high

Mantle-derived trace element variability in olivines and their melt inclusions
Autor: Stefan Weyer, David A. Neave, Martin Oeser, Katsura Kobayashi, Oliver Shorttle
Publikováno v: Neave, D A, Shorttle, O, Oeser, M, Weyer, S & Kobayashi, K 2018, ' Mantle-derived trace element variability in olivines and their melt inclusions ', Earth and Planetary Science Letters, vol. 483, pp. 90-104 . https://doi.org/10.1016/j.epsl.2017.12.014
Trace element variability in oceanic basalts is commonly used to constrain the physics of mantle melting and the chemistry of Earth's deep interior. However, the geochemical properties of mantle melts are often overprinted by mixing and crystallisati
