Research interests & CV


Metamorphic petrochronology: Analysis of phase relation, thermobarometry and in situ geochronology in order to solve fundamental problems in the fields of:

  • Determination of P-T-t-d paths of individual samples
  • Micro-mapping technique: development and improvement of XMapTools software
  • Petrogenesis of metamorphic rocks and scale of equilibrium domains: local bulk composition measurements and inversion of forward thermodynamic models (programs: Bingo-Antidote & GRTMOD)
  • Thermodynamic properties and models of complex solid solutions; kinetics and phase equilibria
  • Micro-dating techniques: LA-ICP-MS and SIMS measurements (U-Th-Pb, allanite, monazite and zircon)
  • Geodynamic and structural evolution of orogenic belts: Internal western Alps (Briançonnais, Sesia and Liguro-Piémontais zones) and Himalaya (Western syntaxe)

Computers programs


New analytical techniques have recently come into play that transform raw electron microprobe X-ray images to maps of oxide concentration, which then are used to depict the spatial distribution of each mineral phase. I developed and I’m improving XMapTools (Lanari et al., 2014), a MATLAB©-based program for the X-ray and trace element LA-ICPMS images processing and thermobarometry. The data reduction involves several steps such as (i) analytical standardization, (ii) classification, (iii) structural formulae calculation and (iv) estimation of P-T conditions. In order to estimate P-T conditions of crystallization, XMapTools include a set of ~50 empirical and semi-empirical thermobarometry functions and can easily be coupled with forward (i.e. Gibbs free energy minimization) and inverse (i.e. multi-equilibrium) modeling calculations.
