The volcanoes we study Understanding volcanism requires the acquisition of field data: visible and thermal imagery, geophysical campaigns, gas, rock and ash sampling for petrological and geochemical analyses, mapping of deposits and destruction, etc. Our targets depend on the current activity, research themes and our collaborations with French laboratories and observatories, as well as partn...

The Magmas and Volcanoes Laboratory (LMV) is a joint research unit of Clermont-Auvergne University, affiliated with the Centre National de la Recherche Scientifique (CNRS, UMR 6524), the Institut de Recherche pour le Développement (IRD, UMR 163). It is one of two laboratories of the Clermont-Ferrand Global Physics Observatory (OPGC). The LMV is also the Earth Science teaching department of Clermon...

TIMS Triton XT (Thermo-Ionisation Mass Spectrometer), from ThermoFisher Scientific, has been installed in the Laboratory Magmas and Volcans since September 2016. This instrument was purchased as part of Maud Boyet's ERC ISOREE project ISOREE “New insight into the origin of the Earth, its bulk composition and its early evolution”. This instrument is spectrometer for isotope analy...

TIMS Triton (Thermo-Ionisation Mass Spectrometer), from ThermoFisher Scientific, has been installed in the Laboratory Magmas and Volcans since January 2005. This instrument was co-financed by INSU, the University Blaise Pascal from the Auvergne Region and Regional FEDER funds. This instrument is a spectrometer for isotope analysis. It is equipped with 9 Faraday cages allowing the simultane...

Mise en solution par fusion alcaline The technique uses fluxing agents : Mixing: fluxing agent/sample, lowers the melting point of the sample. The main fluxing agents contain borates: LiBO2 / sample powder. Melting is generally done in graphite crucibles using a magnetic induction furnace. The obtained bead is dissolved in an acidified solution (HNO3 1%). The total volume is 200ml. ...
