The Montney Formation is a Lower Triassic, siliciclastic-dominant unit in the subsurface of west-central Alberta and northeast British Columbia (Fig. 11). Throughout its area of occurrence it is underlain unconformably by either Permian or Carboniferous strata and overlain abruptly, and probably unconformably, by the Middle Triassic Doig Formation. Towards its eastern outcrop limit Jurassic strata truncate successively older Montney beds.

Although strata equivalent to the Montney in outcrop have been subdivided into a number of named members (see Davies et al., 1997, for a brief review), generally it has proven difficult to correlate the outcropping units into...
