“…No normalization was conducted, as the raw ratios are suitable accurate to assess -LA-ICPMS U-Pb isotope mapping approach was undertaken at the Institut des Sciences Analytiques et de Physico-Chimie pour l'Environnement et les Matériaux (IPREM) Laboratory (Pau, France). All the 29 samples were analysed with a 257 nm femtosecond laser ablation system (Lambda3, Nexeya, Bordeaux, France) coupled to an HR-ICPMS Element XR (ThermoFisher Scientific, Bremen, Germany) fitted with the Jet Interface (Donard et al, 2015). The method is based on the construction of isotopic maps of the elements of interest for dating (U, Pb, Th) from ablation along lines, with ages calculated from the pixel values (Hoareau et al, 2020).…”

Abstract. We report the results of a multiproxy study that combines structural analysis of a fracture–stylolite network and isotopic characterization of calcite vein cements and/or fault coating. Together with new paleopiezometric and radiometric constraints on burial evolution and deformation timing, these results provide a first-order picture of the regional fluid systems and pathways that were present during the main stages of contraction in the Tuscan Nappe and Umbria–Marche Apennine Ridge (northern Apennines). We reconstruct four steps of deformation at the scale of the belt: burial-related stylolitization, Apenninic-related layer-parallel shortening with a contraction trending NE–SW, local extension related to folding, and late-stage fold tightening under a contraction still striking NE–SW. We combine the paleopiezometric inversion of the roughness of sedimentary stylolites – that constrains the range of burial depth of strata prior to layer-parallel shortening – with burial models and U–Pb absolute dating of fault coatings in order to determine the timing of development of mesostructures. In the western part of the ridge, layer-parallel shortening started in Langhian time (∼15 Ma), and then folding started at Tortonian time (∼8 Ma); late-stage fold tightening started by the early Pliocene (∼5 Ma) and likely lasted until recent/modern extension occurred (∼3 Ma onward). The textural and geochemical (δ18O, δ13C, Δ47CO2 and 87Sr∕86Sr) study of calcite vein cements and fault coatings reveals that most of the fluids involved in the belt during deformation either are local or flowed laterally from the same reservoir. However, the western edge of the ridge recorded pulses of eastward migration of hydrothermal fluids (>140 ∘C), driven by the tectonic contraction and by the difference in structural style of the subsurface between the eastern Tuscan Nappe and the Umbria–Marche Apennine Ridge.

“…This femtosecond laser is coupled to an ICP-MS Element Xr Jet Interface (Thermo Fisher Scientific, Bremen, Germany). This single-sector field mass spectrometer has the specificity of a double focusing of the ions: this offers a better sensitivity and a background noise reduced by a factor of 10 compared to conventional ICP-MS systems, but it also leads to better detection limits and more accurate and reproducible measurements of the isotopic ratios [5,6,7]. This particular combination allows to produce maps of the isotopes relevant for U/Th dating ( 238 U, 235 U, 234 U, 230 Th and 232 Th), while necessitating less than 1 mg of material [8].…”

To overcome the problems associated with the traditional U-series dating protocol (large amount of sample required, possible contamination during preparation and consideration of sample contamination in the past), we present a new approach using isotope mapping of radioelements produced by femtosecond laser ablation coupled with high resolution mass spectrometry (LA-fs HR-ICP-MS). This protocol, developed and validated on different carbonate supports, has been applied to a series of archaeological biominerals (shells, teeth, calcitic crusts). A high resolution of a few micrometres has been achieved, as well as a significant improvement of the sensitivity. This allows to obtain U/Th ages with minimal sampling (< 1mg), even though only ultra-traces of uranium (sub-ppb) are present. The isotope mapping approach also allows a real study of the material, highlighting areas potentially contaminated with detrital thorium, but also areas that have experienced leaching. The potential of this method and its limitations are discussed.

“…Uranioaren konposizio isotopikoa desberdina da ondoren izango duen erabileraren arabera (9. irudia). Ondorioz, markatzaileen identifikazioa beharrezkoa da material nuklearraren trazabilitatearen jarraipena egiteko [80]. Hori dela eta, gaiari buruz adituak direnek (JRC Institute for Transuranium Elements, JRC-ITU) funtsezkoak diren parametroen identifikazioaren eta ezarpenaren garrantzia azpimarratzen dute behin eta berriz [81].…”

Abstract:Since the early 80s, laser-ablation inductively-coupled-plasma mass spectrometry (LA-ICPMS) has been widely explored and nowadays is considered to be one of the most versatile analytical techniques for the direct trace elemental and isotopic analyses of solid samples. The most remarkable features are ease of use, fast sample throughput, limited sample damages, high sensitivity and wide dynamic range which allows the simultaneous acquisition of major and trace elements, as well as the meas-EKAIA 31.indd 45 EKAIA 31.indd 45
