What is Bingo-Antidote?
Bingo-Antidote is an XMapTools’ add-on developed by Pierre Lanari and Erik Duesterhoeft offering a new modelling strategy based on iterative thermodynamic models, integrated with quantitative compositional mapping.
What paper should I read to learn more about this technique?
There are two publications so far reporting results obtained with Bingo-Antidote: Lanari & Engi (2017) and Lanari & Duesterhoeft (2019). Note that the paper of Lanari & Duesterhoeft (2019) includes a general review on thermodynamic modelling and also provides an example showing a nice application of Bingo-Antidote.

When will the first public version of Bingo-Antidote be released?
This is still unclear, but it will not be before 2020!
Is there any way to try the program before that?
Absolutely, a beta version of Bingo-Antidote will be provided to the participants of the pre-Goldschmidt short course “Modeling Local Phase Equilibria – An introduction to Theriak-Domino, XMapTools and Bingo-Antidote” in Barcelona (August 17-18, 2019). Information: http://barcelona2019.petrochronology.org
Note that a participation to this short course is a requirement to join the beta program of Bingo-Antidote.
In which cases should I consider using Bingo-Antidote?
As soon as spatial heterogeneities can control local mineral assemblages and that the bulk rock composition is not relevant for modelling. We also recommend using Bingo-Antidote in samples in which minerals exhibit moderate to strong compositional zoning.
In a more general way, Bingo-Antidote offers several options to optimise the forward part of the model based on the mineralogical record preserved in your rock. It reduces the number of hypotheses required when for instance constructing a pseudosection.
This strategy is also a good alternative to inverse models (average PTor Tweeq) as discussed in Lanari & Duesterhoeft (2019).
When will the next papers (method, program description) be published?
As soon as possible! But unlikely before end of 2019, beginning of 2020.
How can I support the development of Bingo-Antidote?
- Join us for the short course in Barcelona.
- We are also looking for samples showing a well-equilibrated mineral assemblage with no (or limited) compositional zoning. Published material is ideal. Our goal is to acquire compositional maps for illustration purposes and also to use them as teaching material. Please contact us if you wish to contribute.
