Polyphase Glacigenic Deformation of Advance Glaciofluvial Sediments, Near Big Creek, British Colombia

Abstract: Deformation structures were observed in glaciofluvial sediments near Big Creek, central British Columbia. These sediments record a sequence of polyphase deformation resulting from the advance and retreat of the Late Wisconsinan (Fraser Glaciation) Cordilleran Ice Sheet. Deformation is attributed to ductile then brittle failure resulting from: (a) horizontal compression and loading as ice advanced over saturated sediments; followed by (b) lateral extension then (c) compression under frozen conditions during gla… Show more

Glaciotectonic studies of deposits associated with the Cordilleran Ice Sheet (CIS) have been conducted along the west coast of British Columbia (BC) (Hicock & Dreimanis 1985;Brown et al 1987;Parkin & Hicock 1989;Hicock & Fuller 1995;Hicock & Lian 1999;Lian & Hicock 2010) and in the interior of BC (Broster et al 1979;Broster & Clague 1987;Broster 1991;Huntley & Broster 1993;Lian & Hicock 2000;Lian et al 2003). This work has focused largely on the sedimentology, architecture, macro-(pebble-) fabric and structural geology of glacigenic sediments and glacially affected bedrock as observed in the field at the macroscale.…”
