Also known as Sub-Section PRG-1, Sample #1015, Alberta (Brazeau Formation)
Where: Alberta, Canada (52.7° N, 116.0° W: paleocoordinates 60.9° N, 79.8° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Brazeau Formation, Campanian (83.5 - 70.6 Ma)
• The top of the section is approximately 1000 ft above the mouth of Chungo Creek; the base is delineated by the Wapiabi-Brazeau Formation contact which is found just below Brown Creek. The two creeks are less than 3 miles apart and both flow into the north side of the Blackstone River.
•PRG-1-1015 is from the section of the Brazeau Formation which is Belly River Equivalent.
• formation-level stratigraphic resolution
Environment/lithology: terrestrial; shale
Size class: microfossils
Preservation: original sporopollenin
Collection methods: surface (in situ), chemical, sieve,
• Method involved boiling 500-800 grams of rock in aqueous solution of Quaternary-O until dissolved, washing sediment through 4 screens (1000, 297, 125, 74 microns), and some additional treatment in hydrochloric and hydroflouric acids was used to remove carbonate and silicate minerals. The highly carbonized samples were oxidized with Schultze's solution and 10% potassium carbonate to lighten the spore color. The slides are now stored in the palynological collection of the Department of Geology, the University of Calgary.
