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...

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. ...
