Résumé(disponible en anglais seulement)
This report presents a detailed measured section through the Fernie Formation at Pink Mountain, Trutch map area (NTS 94G), northeast British Columbia. At Pink Mountain, the Fernie Formation can be subdivided into a lower member, dominated by dark-weathering, calcareous siltstone and shale, and an upper member consisting of dark-weathering, noncalcareous siltstone and shale with lesser sandstone. Both members were deposited in quietwater marine settings. A synthesis of new fossil collections with earlier reports from Pink Mountain indicates that the lower member ranges in age from Early Jurassic to at least Middle Jurassic, whereas the upper member is of Late Jurassic age. The two members are separated by a regional unconformity, which, at Pink Mountain, represents at least three stages. Strata in the lower member lack the chert and limestone beds that characterize the Nordegg Member in its type area and should not be assigned to that unit, but may be correlative with the recently proposed Gordondale Member.
