Clean rooms:

  • class 10.000, dressing room;
  • 2 class 1000 rooms for sample preparation (acid digestion), distillation of reagents and purification of elements to be analyzed (Sr, REE, B, Cr) through ion exchange chromatography;
  • 1 class 100 room for sample preparation (acid digestion) and purification of elements to be analyzed through ion exchange chromatography (Pb and mycroanalis of Sr.

Cleanrooms are equipped with hoods with ejection system of acid vapors (including HF), hot plates, sub-boiled water and acid distillation systems, including three Savillex DST-1000, used for H2O, HCl and HNO3 purification, respectively, a precision balance Sartorius Cubis (ripetibility ±0.015 mg), several sets of columns for element separation from the matrix through ion exchange chromatography.

METHODS

Routine isotope systems at Neptune-TIMS lab include isotope ratio measurements, as well as the content via isotope dilution, of following elements: B, Cr, Sr, Nd and Pb.

In particular, we run measurement of:

  • B isotope composition on borosilicates, borates, rocks and silicate minerals, carbonate minerals and fluid matrices such as volcanic, geothermal, thermal waters and freshwaters.
  • Pb isotopic composition on silicate and carbonate rocks and minerals, fluid matrices, industrial manufacts (e.g. metals) archaeological manufacts (coins, other manufacts).
  • Nd isotope composition on silicate and carbonate rocks and minerals, and fluid matrices such as volcanic, geothermal, thermal waters and freshwaters.
  • Cr isotope composition on aqueous matrices and mafic and ultramafic silicate rocks.
  • Elemental contents via isotope dilution.

APPLICATIONS

The above listed analytical methods are applied to a broad spectrum of studies concerning isotopic fingerprinting in several areas of Earth Sciences and Environment lato sensu, including petrology and isotope geochemistry studies on igneous, metamorphic and sedimentary rocks, isotope hydrology, water-rock interactions, indirect geochronology of marine carbonates, pollution tracking, forensic geochemistry, isotope fingerprinting applied to cultural heritage.

It is worth to note the role played by this laboratory in analytical standards intercalibration projects. In 2001 this lab, in collaboration with the IAEA, organized an international inter-calibration exercise for the measurement of the isotopic composition and the boron concentration of solid and liquid matrices. Since then, the TIMS laboratory IGG-Pisa is the holder and distributor of the liquid matrix standards labeled B1 to B3, and B4 to B8 solid matrix standards.

SCIENTIFIC INTEREST

Research activities supported by this laboratory cover a wide spectrum in the framework of Earth and Environmental Sciences. Main active themes include:

  • Subduction and deep recycling of material in convergence-collision areas (from volcanic arc, to subducted and exhumed rocks)
  • magmatism in converging and diverging regions (Mediterranean Area, from Spain to Iran, Eastern Pacific, Ethiopia, Central and South America).
  • Research in Antarctica (Relations between magmatism and tectonic evolution of North Victoria Land; paleo-climatic reconstructions through the study of volcanic products)
  • geothermal and thermal systems: water-rock interactions, fluid tracking (origin, characteristics, circulation times and pathways), geothermal paragenesis
  • Origin and evolution of mud volcanoes and fossil salt waters (Central Apennines)
  • Isotopic Applications on active landslides studies
  • Aquifers and river basins: recharge, weathering and anthropogenic pollution
  • Geochronology of marine carbonates through Sr isotope composition
  • Isotope fingerprinting of anthropogenic and geogenic environmental pollutants (B, Pb, Cr, heavy metals)
