Surficial geology and Pleistocene stratigraphy from Deep Bay to Nanoose Harbour, Vancouver Island, British Columbia / [by] J.M. Bednarski. : M183-2/7681E-PDF
A detailed study of the surficial geology of the east coast of Vancouver Island from Deep Bay to Nanoose Harbour, British Columbia was undertaken as part of the Nanaimo Lowland Ground Water Assessment Project. This paper describes the results of the study and introduces a surficial geology map incorporating the Pleistocene stratigraphy derived from new seismic reflection surveys, boreholes and existing water well data. The unconsolidated sediment cover is greater than 100 m thick in places with most deposits derived from two previous glaciations that are separated by non-glacial fluvial and marine sediments. Major sedimentation also occurred in the valleys immediately after the last glaciation, a time of rapidly falling sea level and abundant meltwater. Modern alluvium is confined to the lower reaches of the larger rivers.
