JMDplots vignettes

CHNOSZ supplementary plots (2019)

This vignette runs the code to make most of the supplementary figures from the following paper:

Dick JM. 2019. CHNOSZ: Thermodynamic calculations and diagrams for geochemistry. Frontiers in Earth Science 7: 180. doi: 10.3389/feart.2019.00180

This vignette was compiled on 2024-03-11 with JMDplots 1.2.19-11 and CHNOSZ 2.1.0-5.
