At least six infilled paleochannels of variable depth are present within the study area, although their exact geometry remains unknown. Stratigraphic correlation of the units within these channels is problematic due to the lack of samples and radiometric ages. Till matrices display homogeneity within three metres of the till - substrate contact, indicating rapid rates of substrate debris entrainment and dilution within the till column. Terminal grade of the entrained material determines the preservation rate of anomalous material within the till column, and can be used to determine glacial transportation distances. In the study area, low and high terminal grades of the underlying bedrock units and the DIMs, respectively, in conjunction with the position of anomalous samples within the till column, indicate debris entrainment within the ice was rapid and the distance of transport was short.
Most anomalous samples appear to have come from sources within a few kilometres distance.
In the Puskwaskau region, the sources are even closer, likely within one kilometre. Dispersal patterns or trends can be a significant tool in exploration in the Winagami area, provided that they are analysed in conjunction with bedrock topography, drift thickness and glacial history. Information on the March Lecture will be sent in the near future.
