xmaptools_logo4

Quantitative compositional maps are used to depict the spatial distribution and compositional variability of mineral phases in thin sections of rock. I developed and I am improving XMapTools (Lanari et al., 2014; Lanari et al., 2018), a MATLAB©-based software solution for processing X-ray and trace element LA-ICPMS maps as well as to determine local bulk composition and perform thermobarometry analysis. The data reduction involves several steps such as (i) analytical standardization, (ii) classification, (iii) structural formulas calculation and (iv) determination of P-T conditions of formation or re-quilibration. XMapTools includes six chemical modules for data visualisation and a large set of  empirical and semi-empirical thermobarometry functions.

GRTMOD

GRTMOD is a program modeling garnet growth and resorption in metamorphic rocks. The main routine of GRTMOD uses an inverse approach to fit the garnet composition predicted by thermodynamic forward models with the one measured by the mean of standardized X-ray maps. The main goal of GRTMOD is to optimize pressure, temperature and the local effective bulk composition in order to accurately model the successive growth zones of natural garnet. The Gibbs free energy minimization is done with Theriak-Domino (link), originally  using the add-on TheriakD (link).

Bingo-Antidote (XThermoTools)

Primarily Bingo-Antidote can be described as an inverse Theriak (link), because it uses the information provided by XMapTools to calculate the most likelihood P-T equilibrium conditions for a given metamorphic assemblage. This new strategy combines the strengths of forward Gibbs free energy minimization models with the intuitive approach of inverse thermobarometry models. Bingo-Antidote is available as a standalone program, or embedded into XMapTools using the add-on XThermoTools. The *public* version of XThermoTools is not expected to be published before 2020. Contact me if you are interested in using Bingo-Antidote.

SSAC & Trinity

SSAC is a program for the SIMS data processing and TRINITY a program to process LA-ICP-MS data. These programs allows to calculate U-Th-Pb ages for Allanite and Zircon from SIMS and LA-ICP-MS spot-analyses. TRINITY was developed by M. Burn (PhD student, University of Bern).

Meamp

Meamp is a program for for multi-equilibrium calculations using different thermodynamic datasets and solid solution models. This program allows standard state properties and solid solution parameters adjustement by nonlinerar regression using experimental or natural data. A description of Meamp is available, in french, in my Ph.D. thesis (download here). This program is not available for public use.
