At the moment, we can only plot Ternary diagrams as an overlay function inside Xplot, which is useful for visualization on some data, but there is no easy workflow for users to input their data and it does not provide a calibrated, true display.
It’s possible to create nice-looking displays, such as the header image displaying a Ternary diagram across multiple intervals.
As this tcl/Loglan uses three standard wireline logs to represent each ternary axis, it could be used for all sorts of things (phase diagram, clastic analysis etc.) by chaining other Loglans to create the required data.
The accompanying tcl script, ternary.tcl, provides an automated way to run the Loglan and create display ternary Xplots.
The tcl script launches the Loglan, ternary_generator, that transforms 3-component logs (e.g. three mineral volumes) into Cartesian space so that the data can be plotted inside a Xplot.
The script will then generate a new Xplot by taking the log names used in the Loglan and then using these logs on each individual Ternary axis. It will then display the logs that have been calculated.
