This R'Equip proposal seeks 50 % matching funds for acquisition of a XRF core-scanner, preferably with digital radiography option. This scanner will complement the core-scanning facility at the University of Bern consisting to date of a petrophysical multisensor core logger (MSCL Geotek) and a reflectance spectroscopy core scanner (Specim) through offering a high-resolution elemental scanner producing a wealth of geochemical data. The instrument uses an X-Ray source to determine semiquantitatively a full range of elements (Al and heavier) in a non-destructive fashion down to ppm levels in vertical core resolutions of up to 100 µm. One of the models, the Itrax instrument, furthermore offers a digital X-ray radiography option with a resolution of up to 20 µm. Main use of this instrument will be the continuous and high-resolution scanning of sediment cores to yield invaluable paleo-proxy data (e.g. climate, runoff, human impact). The same tool, however, will also be applied towards hardrock cores and other archives, such as speleothems and tree rings.To date, only one XRF core-scanner exists in Switzerland (ETHZ), which cannot cover the need for this analytical technique. Several projects of various Swiss research groups will start in the near future, which will produce hundreds of meters of drill cores that will be stored and analyzed in Switzerland. The instrument will be hosted at the University of Bern but would be available for all research groups in Switzerland working with drill cores or suitable samples. This new capacity, together with the novel radiography option, will provide urgently needed analytical infrastructure to exploit the upcoming core samples in a state-of-the-art manner. Key applications will be paleoclimatic and paleoenvironmental studies using lacustrine and marine sediment cores, incl. determinations of changes in detrital supply and erosional patterns, provenance studies, change in redox-state of sedimentary basin and signatures of anthropogenic pollution. The radiography option furthermore allows high-resolution density analysis that can be matched with XRF elemental data in order to investigate nature and origin of sedimentary structure and tree rings. In this proposal, we present 12 projects lead by groups from Universities of Bern, Geneva and Basel that all rely on this XRF core-scanning option.
