- •
25 dune field sites were assessed for compositional heterogeneity using THEMIS.
- •
Four sites exhibit spatial heterogeneity in composition across the dune field.
- •
Particle size and olivine abundance positively correlated in two sites.
- •
Aeolian sorting likely not major factor in large scale surface composition variations.
