    The understanding of fossilization mechanisms at the nanoscale remains extremely challenging despite its fundamental interest and its implications for paleontology, archaeology, geoscience, and environmental and material sciences. The mineralization mechanism by which c...

    International audience; Medieval champlevé enamelled objects are from copper sheets decorated with glass. The enamels were analysed by Raman spectroscopy to study the compositional differences in the glass matrix. Additional analyses were carried out by element analytic...

    One of the greatest benefits of synchrotron radiation is the ability to perform chemical speciation analysis through X-ray absorption spectroscopies (XAS). XAS imaging of large sample areas can be performed with either full-field or raster-scanning modalities. A common ...

    AbstractPrecambrian cellular remains frequently have simple morphologies, micrometric dimensions and are poorly preserved, imposing severe analytical and interpretational challenges, especially for irrefutable attestations of biogenicity. The 1.88 Ga Gunflint biota is a...

    The in situ two-dimensional (2D) and 3D imaging of the chemical speciation of organic fossils is an unsolved problem in paleontology and cultural heritage. Here, we use x-ray Raman scattering (XRS)–based imaging at the carbon K-edge to form 2D and 3D images of the carbo...

    International audience; We provide in this study a new application of laser-induced breakdown spectroscopy (LIBS) to evaluate whether ancient bones contain sufficient organic material before radiocarbon dating, which can avoid a complex preliminary analysis on the sampl...

    International audience; The detailed description of corrosion processes in ancient and historical metal artifacts currently relies on the in-depth study of prepared cross sections. The in-plane elemental and phase distributions can be established from a combination of l...
