| Abstract | Surficial sediments in the Coppermine (86O, east half) and Kikerk Lake (86P) sheets were mapped at a 1:125 000 scale. Till blankets and veneers, representing a single till sheet, are the most common
surficial sediments, with exceptionally long drumlinoid features west of Kikerk Lake. Esker and outwash complexes occur throughout the area, serving as potential aggregate resources. Permafrost features include mudboils and solifluction lobes on
till. Coarse grained glaciofluvial and deltaic deposits typically contain large ice-wedge polygons with wide, deeply incised troughs. These features may result from partial or complete meltout of underlying wedge ice, or signify the presence of
massive ground ice at depth resulting in widening of troughs through creep deformation of underlying ice. Marine deposits composed primarily of clayey silt cover much of the coastal plain and are typically ice-rich in the upper 1.5 m, with numerous
but relatively small retrogressive thaw flowslides. |
