Stratigraphy
Formation:Brazeau Local bed:1010
Local order:bottom to top
Stratigraphic resolution:formation
Stratigraphy comments: 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-1-1010 is from the section of the Brazeau Formation which is Belly River Equivalent.
Lithology and environment
Primary lithology: "shale"
Lithology description: shale and silty shale
Environment:terrestrial indet.
Taphonomy
Modes of preservation:original sporopollenin
Size of fossils:microfossils
Collection methods and comments
Collection methods:surface (in situ),chemical,sieve,field collection
Minimum sieve size:0.074 Maximum sieve size:1.000
Reason for describing collection:paleoecologic analysis
Collection method comments: 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.
