Geography
Country:Canada State/province:Alberta
Coordinates: 50.8° North, 111.5° West (view map)
Paleocoordinates:58.1° North, 76.1° West
Basis of coordinate:stated in text
Altitude:648 meters
Geographic resolution:outcrop
Time
Period:Cretaceous Epoch:Late/Upper Cretaceous
Stage:Campanian 10 m.y. bin:Cretaceous 7
Key time interval:Middle Campanian
Age range of interval:83.50000 - 70.60000 m.y. ago
Stratigraphy
Geological group:Belly River Formation:Oldman
Local section:DPP-Brinkman Local bed:-17.5 m
Local order:bottom to top
Stratigraphic resolution:bed
Stratigraphy comments: Microvertebrate sites of Brinkman (1990) are "...placed in stratigraphic sequence by reference to a disconformity located about sixty meters below the base of the Lethbridge Coal (Eberth, 1990). The stratigraphic position of each site is expressed in terms of meteres above or below the disconformity (Fig. 2, Brinkman, 1990)."
Lithology and environment
Primary lithology:tabular,"cross stratification",lag,pebbly,intraclastic silty sandstone
Lithology description: "Microfossils occur in two stacked, poorly-sorted and graded tabular units of silty sandstone...the lowermost unit is 75 cm thick. Well-rounded, platy to oval mudstones intraclasts, some as large as 7 cm in their maximum dimensions, are abundant throughout the unit...Disarticulated unionid valves and gastropod shells are present. The larger unionids are rare and are restricted to the lower portion of the unit while the gastropods are abundant throughout the deposit." (Eberth 1990)
Environment:"channel"
Glacial or sequence phase:transgressive
Geology comments: Characterized as in-channel, coastal plain. Facies association = trough cross-stratified sandstones. Upper flow-regime, tractional plane beds fromed during flood stage. Lag deposits, or plane bed deposits that show horizontal-planar stratification, bed thicknesses exceeding single pebble diameters, normal graded or fining upward texture, and matrix-supported clasts. The disconformity in southern Alberta records a Cordilleran uplift event west of the Park.
