Abstract

In August 2023, the Quaternary stratigraphy of eight sections situated on the Gods and Yakaw rivers, in the Hudson Bay Lowland of northeastern Manitoba, were investigated. The goals of this remote fieldwork were to establish a more complete understanding of the Quaternary history of the region and to collect indicator-mineral samples to assist with drift exploration efforts. This data will enable better mineral-potential assessment for the region, and help to interpret the provenance of tills in this glacially complex area. Ninety-eight till samples were collected for both clast lithological and geochemical analyses, with an additional 33 samples collected for indicator-mineral analysis. Additionally, till-clast fabric measurements were conducted at 55 sample sites to interpret paleo-iceflow direction during deposition. Intertill sorted sediments were documented and sampled whenever possible, using a variety of methods to establish paleoenvironmental conditions and geochronology constraints. [ABSTRACT FROM AUTHOR]
