Description du poste

National geological service, the BRGM is the benchmark public establishment in earth science
applications for managing soil and subsoil resources and risks (www.brgm.fr). Its action is oriented
towards scientific research, support for public policies and international cooperation.
Within the water process and analyses department (DEPA) and in collaboration with georesources
department (DGR), you will participate in research activities to study the geochemical characteristics
of quartz in alluvial systems.

The BRGM Research Fellow will have to carry out the optical and spectral analyses in CL, so as to carry
out the color map (classification) of each type of quartz taken on site. He/she will also be in charge of
the LA-ICP-MS analyses and their processing and interpretation. Finally, she/he will have to compile all
the CL, (EPMA), LA-ICP-MS and LIBS information (provided by a project partner) in order to establish
an identity card of the different types of quartz in the areas concerned. This identity card will be
completed by ESR and OSL response to a (chemical) quartz type. In a second time, the post-doctoral
student will realized similar identity card on quartz from current and fossil sediments.
