AbstractDistinctive airborne K-eU-eTh spectral associations, calibrated by ground spectrometry, define eight discrete domains. Till composition and provenance vary across the test area and vertically within glacial deposits. Till geochemistry (K, U, and Th in <0.063 mm size fraction) differs between airborne spectral domains, but does not correlate with ground spectrometry. This likely reflects compositional differences between size fractions measured by the two methods. Linear correlations indicate that trace metals (Cu, Ni, Cr) are hosted by HNO3-HCl-soluble Mg-bearing minerals.

The eTh-rich A1 and A2 spectral domains reflect sandstone-rich till and sandstone outcrop. The B domain on the northwest is part of a regional Quaternary glacial dispersal train of basement detritus that extends across the eastern Athabasca Basin. The D domain is curvilinear, ribbon-like, K- and eU-rich, comprises predominantly basement-rich till with distinctive large calc-alkaline granitic boulders, and its physical-compositional characteristics cannot be explained by simple down-ice dispersal mechanisms as previously proposed.
