TOOLS

In the recent years, we have used, adapted and improved a variety of techniques to analyse in situ minute amounts of organo-(bio)mineral compounds preserved in rock samples. These include: Raman spectrometer coupled to a confocal fluorescence microscope, scanning electron microscope (SEM), Synchrotron-based techniques (SR-µXRF, SR-µXANES and differential phase contrast imaging techniques) and Secondary Ion Mass Spectrometry (SIMS). Central to these achievements is the technical platform PARI of IPGP and access to large infra-structures such as Synchrotron (SOLEIL, ESRF, SLS, Australian Synchrotron) and Ion Probes (CRPG Nancy, Australian National University) facilities.
