Geochemistry Plotting Tools
Create spider diagrams, discrimination diagrams, custom XY and ternary plots, and REE shape coefficients for geochemical data
Plot geochemical data straight from QGIS point layers.
Supports:
- spider diagrams with a choice of normalisations,
- REE shape coefficients (lambda0-lambda4, O'Neill 2016) written to the attribute table,
- tectonic discrimination and rock classification diagrams,
- mineral classification plots, petrophysics cross-plots,
- custom XY and ternary plots built from any element, oxide or numeric field;
- interactive plots linked to the map: selecting points on a plot selects them on the map, and the other way round, and plot styles can be shared with the layer's symbology,
- advanced plotting options: samples can be grouped and styled by category, sized by a field (bubble plots), and summarised with category statistics (mean, median, IQR),
- automatic element and oxide field recognision and conversion to common units.
Firstly developed for the UWA EART3343 lab exercises.
