  • Elemental concentrations are in ppm except for Au and Pt which are in ppb. EC in µS/cm. Spectral scalars are standard output, refer to Noble et al. (2019). n = 193. SSA, specific surface area.

  • * Particle size distribution is for comparison only and currently overestimates clay and silt percentages.
