| dc.description.abstract | The Canadian Cordillera has undergone repeated glacial and interglacial cycles during the Quaternary Period over the last 2.6 million years. In south-central B.C., these cycles have deposited sedimentological evidence that enables researchers to reconstruct glacial dynamics through stratigraphic analysis and geochronological dating. However, existing stratigraphic profiles and radiocarbon dates in the interior of B.C. are limited or possess large age uncertainties. To refine the timing of glacial advance and retreat, this study constructed a high-resolution stratigraphic profile of the Mission Flats exposure in a quarry near Kamloops, B.C. Preliminary results suggest that the area underwent repeated episodes of submersion and reworking due to the growth and retreat of a glacial meltwater lake in response to climatic fluctuations. Unconformities indicate several shifts in depositional environments over time, including a notable erosional surface attributed to the most recent Fraser Glaciation. Additionally, stratigraphic and sedimentological evidence may correlate with previous studies in the area, suggesting deposition dating to Marine Isotope Stage 3, approximately 57,000 years ago. These findings (i) will aid in connecting our understanding of ice-sheet behaviour and paleoenvironments, including paleoclimates, in south-central B.C. and, (ii) will help future understanding of the distribution and provenance of construction aggregate in the region. | |
