5203 |a"The complex glacial geomorphology of east-central Quebec and western Labrador has resulted in conflicting ice sheet reconstructions leaving many questions regarding the behaviour of large ice sheets within their inner regions. Specifically, the ice-flow chronology and subglacial conditions remain poorly constrained. To address this, surficial geology investigations were conducted across the border of Quebec and Labrador. A complex glacial history consisting of five ice-flow phases influenced by regional ice stream dynamics was identified, including a near-complete ice-flow reversal. During each ice-flow phase, the subglacial thermal conditions fluctuated both spatially and temporally, resulting in palimpsest glacial dispersal patterns. Deglacial ages from samples collected as part of this research confirm deglaciation occurred relatively rapidly around 8 ka. The results of this work improve our understanding of the glacial history of an inner region of the Laurentide Ice Sheet and have important implications for mineral exploration in the southern Core Zone area"--Abstract, page 2.
