An Extended Durov plot is a powerful tool for visualizing the chemistry of water samples. They combine two ternary diagrams (cations and anions) with rectangular fields that typically show pH and total dissolved solids (TDS). This layout helps identify hydrochemical facies, mixing processes, and geochemical evolution patterns across multiple water samples.
The template includes labeled axes for all key ions – Ca, Mg, Na+K, Cl, SO₄, and CO₃+HCO₃ – as well as pH and TDS. Sample ID points are color-coded by group classification for easy comparison, and the plot layout makes it simple to interpret complex water chemistry patterns.
Your data sheet just needs one column for each ion group, plus pH, TDS, and an optional grouping or ID column – so adapting the template to your own data is quick and straightforward.
