Got soil geochemistry? Want to get beyond a simple single-element map and to normalise for rock type / sample media? We can help you to extract as much value as possible from your soil geochemistry dataset.

 

Mapping lithology and targeting

  • Objective classification of lithology, alteration or mineralisation from geochemical data.
  • Examine relationships between multiple elements simultaneously.
  • Rapid assessment of trends within the data that may not be apparent with single- or two-element plots.
  • Groupings can inform lithology mapping, exploration targeting, and alteration mapping.

Principal components analysis of 14-element geochemical soil sample dataset, from Marirongoe, Mozambique, groupings informed by Bayesian clustering algorithm. Eigenvectors (arrows) indicate elements influencing the analysis (modified after Sterk et al., 2018).
