Abstract
A well exposed outcrop of the Upper Devonian Imperial Formation at the Imperial River
type section, Northwest Territories, is described and analyzed in detail to evaluate depositional
and sequence stratigraphic models. The formation is divided into lower, middle and upper
intervals, with the present study focusing on the sandstone‐rich middle interval deposits. Eight
facies are described and three facies associations interpreted within the middle interval, which
comprise forty upwards‐ coarsening packages (3 – 20 m thick) at Imperial River. Each upwardscoarsening
package is considered a parasequence, which records the shift from distal to
proximal shelf and shoreface deposits. Analysis of various regional successions of parasequence
stacking patterns, through integration of seismic data, well logs and outcrop data, is used to
refine sediment distribution predictions and develop a revised stratigraphic framework for the
Imperial Formation. The development of regional and local depositional models, should provide
an initial framework for hydrocarbon exploration in the Imperial Formation of the Mackenzie
Corridor.
