A 3-year MNRT-funded (French Government) studentship is
available at the Institut des Sciences de la Terre d'Orléans
(ISTO), Orléans University in France, studying the '
Transition between explosive and effusive volcanic eruptions:
In-situ magma permeability measurements'. The project is
supervised by Caroline Martel. The project aims at determining the
gas percolation threshold and the permeability evolution of
silica-rich melts during decompression (when gas bubbles grow) or
deformation (when gas bubbles deform), using a high-pressure and
high-temperature deformation press of Paterson type equipped with
two porosimeters and X-ray microtomography to characterize the
pore network. The project is both, scientifically challenging
since permeability controls the explosive potential of an erupting
magma and technically challenging since no dynamic permeability
measurements have been performed so far under realistic magma
conditions.
We seek for a highly-motivated student (any nationalities) with a
Master degree in earth science (geophysics, physics, volcanology)
or related subjects.
ISTO is a dynamic and stimulating working
environment with a long expertise in high pressure and high
temperature experimentation, equipped with dedicated facilities
for the study of magma processes. The successful candidate will be
expected to collaborate with members of the MeMoVolc European
Networking (PI T. Druitt) and the working group on Merapi Volcano
(PI J.-P. Métaxian).
The
closing date for application is 21 May 2012 and the
start date of the project is October 2012. Please note that the
pre-selected candidate will have to go for a 10-min audition on 29
May 2012 (skype is possible for non french residents). Further
details of the project and the application process can be found in
french at:

Potential candidates should send a CV, a motivation letter, a
letter of recommendation, and any marks/grades/ranking reports for
the academic degrees,
before 14 May to Caroline Martel at
