\n

The LA-ICP-MS (LASER-ABLATION INDUCTIVELY-COUPLED-PLASMA MASS-SPECTROMETRY) methodology allows for the in situ analysis of trace and minor concentrations of elements from Li to U contained in small volumes of silicates, carbonates, phosphates, and oxides. This technique has countless applications in various fields, including:<\/p>\n\n\n\n

    \n
  • Geological and Planetary Geology (minerals, glasses)<\/li>\n\n\n\n
  • Environmental & Human Health (shells, otoliths, teeth, wood)<\/li>\n\n\n\n
  • Archaeometric (glass, ceramics, bricks, alloys)<\/li>\n\n\n\n
  • Industrial material (glass, alloys)<\/li>\n<\/ul>\n\n\n\n

    Similarly, in situ characterization of U-Th-Pb isotopic composition is performed for geochronological purposes on a wide range of minerals, particularly silicates (zircon and titanite), phosphates (monazite), and oxides (badelleite, rutile). Geochronological analyses can also be conducted on separate rock sections or directly on rock sections, preserving the textural context.<\/p>\n\n\n\n

              Methods and Applications<\/h3><\/div><\/div>
              \n

              The LA-ICP-MS laboratory in Pavia was designed and equipped to conduct elemental and isotopic analyses of small volumes (a few cubic microns) of solid matrices, and therefore finds many applications in earth sciences and biology.<\/p>\n\n\n\n

              The laboratory conducts U-Th-Pb geochronological analyses of accessory minerals such as zircon and monazite, as well as rutile, titanite, and badelleite. The aim of these analyses is to provide temporal constraints on the crystallization of rocks or their tectonic-metamorphic evolution. Geochronological dating is also performed on sedimentary rock samples for provenance studies.<\/p>\n\n\n\n

              The LA-ICP-MS laboratory in Pavia conducts analyses of trace element concentrations (from Li to U) in natural and\/or synthetic solid materials. The laboratory boasts decades of experience determining trace elements in rock-forming minerals, extraterrestrial materials, volcanic glass, gems, bioconstructed carbonates (otoliths, shells, etc.), and synthetic materials such as glass and ceramics, both recent and ancient. In recent years, the laboratory has also acquired considerable experience determining trace elements (primarily heavy metals) in bones, teeth, and wood (e.g., tree rings).<\/p>\n\n\n\n

              LA-ICP-MS analyses can be performed on thin rock sections, preferably >30 \u03bcm thick, or on separate sections embedded in epoxy resin cylinders 1 or 2 inches in diameter and 0.5 cm thick. The analytical spot size can range from 5 to 100 microns in diameter.<\/p>\n\n\n\n

              Project:<\/strong><\/p>\n\n\n\n

              Over the last 10 years, researchers at the LA-ICP-MS laboratory in Pavia have received funding as proposers of or participants in scientific projects such as: MIUR \u2013 PRIN (2005; 2007; 2009; 2015; 2017), PNRA (2010; 2013), bilateral projects between CNR and CONICET (Argentina; 2013-2014), CARIPLO projects (2013), MEXT projects (Ministry of Science and Technology of Japan). Furthermore, the laboratory has received funding from scientific-technical applied projects, in particular dedicated to the determination of asbestos content in green stones.<\/p>\n\n\n\n

              The laboratory members are involved in ongoing scientific projects concerning the tectonic-magmatic evolution of the Ivrea-Verbano Zone (CNR-CNRS and ICDP 2015 projects) and investigations of the oceanic lithosphere (IODP projects).<\/p>\n\n\n\n
