Equilibrium Assemblage Calculation

• 1、The algorithm is improved to enhance the calculation accuracy and make the boundary of assemblages more smooth.

   Especially around the liquidus, where the original version was often messy, this update is a significant improvement. However, there will still be some irregular boundary curves sometimes. This is mainly because the content of some phases is very low (0.01% magnitude) in some regions, and the phases whether exist has very little change in Gibbs free energy of the system.

• 2, In some operator systems using commas as decimal separators, some errors will be generated in GeoPS. Because in the previous version, the thermodynamic datasets are saved in CSV format, and the value read by GeoPS will be incorrect while the computer uses commas as decimal separators. In the updated version, all datasets are saved in binary format to avoid the bug about different decimal separators.

• 3, The a-x models of Holland et al., 2018 have been available in GeoPS

• 4, Changed the rule of excluding phase.

   previous, if excluding a phase, then all the phases made by this phase will be excluded. e.g. if ru is excluded, then tbi, tts, etc also will be excluded.

   Updated, if excluding a phase, only this phase will be excluded.

• 5, For chemical components, except input chemical content, but also can input chemical potential.

   While using chemical potential, a prefix “mu” should be added. For example, “mu -1234567”.

   Note, the chemical potential should be in the right range, otherwise, GeoPS can’t output reasonable results.

Isopleth caculation

• 6， For calculating phase mode isopleths, an option of include or not the fluid is added.

  

• 7, The updated GeoPS added a function for calculating the isopleths of specific site occupancy for each mineral (for example site Na ( A ) for the glaucophane mineral).

  

• 8, While there is an immiscibility gap in some a-x models, GeoPS added an option to observe the isopleth by choosing the highest or lowest chemical composition rather than an average.   

• 9, Isoplethes of density, G, H, S, V, etc of system and phases can be created.

  

• 10, Updated version improved the setting of filled and line's color.

   Users are allowed to move, add or delete the control nodes of gradient color. Right-click and drag to move the position of the control node. Click the control node to set the color; Select a node and press the del key to delete the selected control node. Double-click to add a control node.

  

• 11, The composition isopleth of minerals has two modals: apfu and wt%.

Others

• 12, For outputting results, the density and G H S V can be outputted in the updated version.

• 13, Fixed the bug of the Zr-bearing melt model.
