To perpetuate, preserve, enhance and develop GET’s expertise in experimentation and analytical techniques

The GET is equipped with an exceptional range of instruments: analytical instruments, research equipment and materials, specific rooms, etc. Most of these instruments are grouped together in a common service or technical platform for use by the community. Other equipments, much more specific and answering a particular need, are only used by some researchers.

Geochemistry and Experimentation

Coordinators: Jeroen SONKE et Jonathan PRUNIER

Missions

The Geochemistry and Experimentation department gathers a set of human power, instrumental, and analytical means allowing support to research projects in geochemistry. The department hosts the production of experimental samples, the treatment of all types of samples (natural or experimental, solid or liquid) to allow their analysis in elementary concentrations (from ultra-trace to major) and/or isotopic analysis (stable, radiogenic…), even in additional dimensions by coupling (speciation, in-situ…).

Services and platforms

• Chemical analyses
• Clean room
• ICP-MS
• TIMS
• GC-IRMS
• Experimental geochemistry-mineralogy
• Mercury
• Datations

Petrology and Mineralogy

Coordinator: Stéfano SALVI

Missions

The Petrology and Mineralogy department gathers a set of human power, analytical, and instrumental means aiming at supporting the characterization of rocks and minerals as well as other solid materials.

Services and platforms

• Lithopreparation
• Metallogeny-fluid Inclusions
• SEM
• X-ray diffraction – X-ray fluorescence
• Microscopy
• Grinding and mineral Separation
• Microanalyses by electronic probe Raimond Castaing – UMS 3623

Geophysics and Positioning

Coordinator: Loic DRIGO

Missions

The Geophysics and Positioning cluster brings together a set of instrumental, analytical, and software resources supporting research conducted at global to regional scales on Earth observation and reference systems, on the structure and internal dynamics of the globe, and the study of fluid envelopes. It relies on various observation platforms (gravimetry, magnetism, subsurface geophysics, GNSS, and InSAR) contributing to national research infrastructures and observation services, two of which are also accredited within the Carnot Extra&Co scheme.

Services and platforms

• Magnetism
• Gravimetry
• InSAR
• GNSS
• Subsurface geophysics

Transversal services

Missions

The services bring transversal skills and knowledge to the different teams, axes, and poles of the laboratory. Their know-how allows advanced instrumental developments, essential in our projects.

• Electronic facility
• Mechanical facility

The instruments are grouped into common services and technical platforms. In a common service, it is not necessary to be an expert to acquire data. The objective is to be able to perform recurrent analyses of a known and constant level, which implies a quality approach. In a technical platform, it is the researcher himself who performs the experiments or analyses. Each experiment is unique and perfectly adapted to the scientific problem treated.
