About VESIcal

VESIcal is an open-source thermodynamic model engine for mixed volatile (H2O-CO2) solubility in silicate melts. It was designed by Kayla Iacovino, Simon Matthews, Penny Wieser, Gordon Moore, and Florence Begue in 2021.

The VESIcal Manuscripts

Two VESIcal manuscripts serve, along with this documentation, as a user’s guide and introduction to VESIcal. The Part I manuscript is available as an executable jupyter notebook or as a static PDF published in the journal Earth and Space Science. Part II is available as a PDF with jupyter notebooks as supplementary files.

The manuscript version of VESIcal Part I (v 1.0.1) is archived on zenodo with a citable doi at https://zenodo.org/record/5095382

How to Cite VESIcal

To cite computations done using VESIcal, please cite the in prep manuscript, the VESIcal version number, as well as the model(s) used. For example: “Calculations were performed using VESIcal (v. 1.0.1; Iacovino et al., 2021) with the models of Shishkina et al. (2014) and Dixon (1997; “VolatileCalc”).” The web-app always runs on the most up-to-date version of the VESIcal code, but it is best practice to note if the web-app was used (“Calculations were perforumed using the VESIcal web-app (v. 1.0.1; Iacovino et al., 2021)…”). We also encourage users to be as explicit as possible as to the conditions used for modelling. This includes stating the pressure, temperature, volatile concentration, and bulk magma composition used in modelling. In the best case, VESIcal users will provide their code (e.g., as a jupyter notebook or .py file) along with their publication such that it can be easily replicated.
