| Abstract/Description or Keywords |
Shuswap Lake is a glacially-over-deepened ﾑfiord lake'. Single-channel seismic reflection data, identifies a tripartite infill stratigraphy up to 800 m thick preserved in bedrock basins eroded as much as 298 m below sea level. A similar tripartite stratigraphy is exposed in nearby outcrops along the valley of the South Thompson River and allows interpretation of age and depositional settings for the infill identified on seismic records. In Shuswap Lake, the lowermost seismic-stratigraphic sequence (SSSI), up to 407 m thick, shows chaotic seismic facies with large-scale diffractions and fills axial parts of V-shaped bedrock basins. Outcrop data suggest that this sequence consists of subaqueously-deposited, ice-contact silts, sands and gravels deposited in a deep (1 km?) ice-frontal lake during late Wisconsin deglaciation (ca. 10 ka). |
