MAGEMinApp.jl interface

The graphic user interface includes 4 main tabs, 3 for phase equilibrium calculation and 2 for supporting information.

This tab allows you to generate and post-process several types of phase diagrams including P-T, T-X, P-X, PT-X and T-Tpolymetamorphic. The main tab is divided in 3 sub-tabs: Setup, Diagram and Trace-emements.

Available thermodynamic database are presented available here. All other options/parameters are detailed below.

1. Phase diagram tab

1.1. Setup panel

Setup

Caption

Thermodynamic database - select among available thermodynamic database Dataset - select among available thermodynamic dataset Phase selection - click to expand and deactivate unwanted pure and solution phase models from consideration Diagram type - select diagram type amont P-T, P-X, T-X, PT-X and T-T polymetamorphic Solidus H2O-saturated - do you want to saturate the first melt in water? TE predictive model - do you want to predict trace-element partitioning at suprasolidus conditions? Pressure [kbar] - minimum and maximum pressure Temperature [°C] - minimum and maximum temperature Initial grid subdivision - choose the initial resolution of the grid Refinement type - can be phase boundary or dominant endmember Refinement levels - Starting level of refinement for the phase diagram Boost mode - choose if you want to make sure of initial guess to compute the next level of refinement Buffer - choose oxygen buffer or if you want to fix oxide activity Solver - choose algorithm used to perform the Gibbs free energy minimization Verbose - choose the level of information display in the julia terminal Specific Cp - do you want to compute latent heat of reaction?

1.2. Bulk-rock composition panel

Setup	Caption
	mol% - select system unit to display the bulk-rock composition Drag and drop - click to open bulk-rock input file or drag and drop the file on the dashed window Bulk-rock list - select among pre-defined or custom bulk-rock composition here Table - the table display the loaded bulk-rock composiion

1.3. General parameters panel

General parameters

Caption

Title - change the name of the phase diagram here Compute phase diagram - button to launch the calculation Save/Load diagram - Here you can save/load a computed diagram together with the state of selected options Directory window - This text window indicates in which folder heavy exported data will be saved e.g., when saving all points information to csv file Help and contact - useful links to post issue and/or ask for support Contributores - list of people that contributed to improve MAGEMinApp

1.4. Display options panel

Display options

Caption

Field - this is where you can choose the displayed field Show grid - displays the adaptive mesh refinement grid Minimum field size - minimum number of cell to consider the mineral assemblage field for labelling Show phase label - hide/show phase labels Show reaction lines - hide/show reaction lines Change line style - here you can overwrite the default black reaction line with a linestyle of your choice Save - saves the defined reaction line style Reset - resets to default black line the reaction line style Update - updates the phase diagram with the newly defined reaction line style Colormap - choose the colormap of the displayed field Value range - defines the range of values considered for the colormap Colormap range - restricts the colormap Set min to white - sets the minimium value of the field to a white color (do not work with Colormap range option) Reverse colormap - true/false reverses the colormap Smooth colormap - here you can choose the interpolation scheme for the field displayed on the phase diagram

1.5. Isopleth panel

Isopleths

Caption

Isopleth type - Pure phase, Solution phase or other. Here you can select which field to be contoured Phase - Select phase to be contoured (if isopleth type is pure or solution phase) Unit - mol/wt Range: min - minimum value for the isocontours Range: step - step for isocontours Range: max - maximum value for the isocontours Line style - change the linestyle of the isocontours (line, dot, dash etc.) Line width - choose the width of the line in pixel Color - choose the color of the isocontours Label size - choose the size of the font for the isocontours labels Add - button to add the isocontour selection to the diagram Displayed window - shows the list of displayed isocontours Hideen window - shows the list of hidden isocontours Hide - button to hide selecter isocontour in the above list Hide all - button to hide all isocontours Show - button to show the selected isocontour from the above hidden list Show all - button to show all hidden isocontours Remove - button to remove selected isocontour Remove all - button to remove all isocontours
