Studied volcanoes

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...

III. Geodynamic Cycle of Volatile Elements

[caption id="attachment_8359" align="alignright" width="407"] Thin section microphotograph under plane polarised light. Characteristic lattice network of low-pressure serpentinisation is visible. Here, the ‘oceanisation’ process (i.e. hydrothermal metamorphism in ocean floor) represented by the networked lizardite, which is even cross cut by antigorite formed during the initial stage of the su...

TIMS Triton

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...

Chemistry room: alkaline fusion

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. ...
