Hubbard, StephenBain, Heather2016-09-282016-09-2820162016http://hdl.handle.net/11023/3342Deep-water slope strata of the Late Cretaceous Nanaimo Group at Hornby and Denman islands, British Columbia, Canada record evidence for a breadth of submarine channel processes. Detailed observations at the scale of facies and stratigraphic architecture provide criteria for recognition and interpretation of long-lived slope channel systems, emphasizing a disparate relationship between stratigraphic and geomorphic surfaces. The composite submarine channel system deposit documented is 19.5 km wide and 1500 m thick, which formed and filled over ~15 Ma. Facies scale analyses highlight conglomeratic channel fill juxtaposed against thin-bedded out-of-channel deposits. Evidence that the channel system was maintained through a variety of processes over a protracted period includes identification of stratigraphic products that record degradational terraces, cyclic steps, mass transport deposition, nested erosion surfaces, and fine- and coarse-grained channel fill deposits. The thesis establishes the Nanaimo Group as an ideal unit to investigate the record of deep-water sediment transfer through slope channels.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
