Petrophysics Platform

High Pressure Lab.

Scientific interests, facilities and publications :

Our understanding on the Earth’s interior, its history and its dynamics relies essentially on our knowledge of the physical properties of the major rock-forming minerals in the deep Earth and on seismogenic activities observed from the surface. Therefore experimental measurements of various geophysical properties are crucial to interpret seismological data from the ‘real’ Earth in order to understand its complex nature and behavior in terms of composition, deformation and thermal structure. Here, at the petrophysics lab. of Geosciences Montpellier, several facilities permit to detects and quantify many physical properties of mantle minerals at the conditions of pressure and temperature of the deep Earth.

The Paterson press at Geosciences Montpellier

The Paterson press has been conceived by Mervyn S. Paterson (1970, 1990) at Australia National University. It is a internally heated gas vessel using argon as pressure medium. This distinctive high pressure and high temperature device has unique advantages : (1) it provides a large hot spot (up to 3 cm) with a quasi-inexistent thermogradient and a temperature sensitivity of +/- 1°C, (2) it is able to hot press large samples (up to 2 cm3), (3) it performs high resolution deformation experiments in both constant load and constant displacement modes.


Paterson press (PI-2) at Geosciences Montpellier
Paterson press (PI-2) at Geosciences Montpellier

Temperature range 300-1250°C
Pressure range : 100-400 MPa, routine at 300 MPa.
Displacement resolution : 2 µm
Load sensitivity : 10 N.
Strain rate range : 10-3 s-1 et 10-6.5 s-1.

Our Paterson press is mainly used for deformation on mantle-derived single crystal and rocks (synthetic or natural) for :
- Deformation experiments of constant load and constant displacement (velocity).
- Diffusion experiments under anhydrous and anhydrous conditions.
- Recrystallization experiments under static or dynamic conditions.
- In situ measurements of physical properties (e.g., electrical conductivity, perméabilité).

The creep apparatus at Geosciences Montpellier

The creep apparatus is for the moment used as a 1-atm furnace with controlled atmosphere in order to have fixed or variable the oxygen fugacity during the measurements of the physical properties.
