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 white chemical room

The clean room is dedicated to wet analysis of samples (sample dissolution and separation of chemical elements). It is a dust-free (pressurized under filtered air) and ventilated area (extraction of acid vapors). It consists mainly of materials/furniture that are inert to acids. The room is divided into several smaller areas dedicated to specific applications.  

MC-ICPMS Neptune

    Instrumentation ThermoFisher Scientific’s MC-ICPMS Neptune Plus (Multiple Collector – Inductively Coupled Plasma -Mass Spectrometry) was funded by the Clervolc Laboratory of Excellence and FEDER funds. It was installed in the laboratory in June 2013. The mass spectrometer includes a high flow rate pumping at the interface (“Jet interface”), a dual focus (electric sector and

Evolution of the Primitive Earth

Origin and composition of the Earth : The precision obtained with the new mass spectrometers has shown that the Earth and the different groups of chondrites were distinguished by very small isotopic differences. In order to constrain the origin and composition of our planet, we wish to measure precisely the isotopic compositions of the primitive

Numerical volcanology

Have also a look at the numerical laboratory The volcanology team has numerical simulation tools, some of which were developed in the laboratory: the VolcFlow code for modelling volcanic flows, deformation models and magma transfers using boundary elements and fictitious domains (DefVolc). This activity is partly based on the computing resources of the UCA’s mesocentre


Have also a look on numerical laboratory Geophysical study of volcanic structures Contact : Philippe Labazuy Technical Manager: Thierry Souriot The internal structure of volcanoes can be studied using geophysical methods. The LMV has a number of facilities for this purpose. See the description and access details. Main techniques used:
