Unit 20, Storm Creek Section, Member 3, Norquay Fm (Permian to of Canada)

Where: Alberta, Canada (50.5° N, 114.7° W: paleocoordinates 20.1° N, 29.2° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: 3 Member (Norquay Formation), Asselian to Asselian (298.9 - 272.3 Ma)

• Unit 20 of Storm Creek Section (counting from the top). Unit 20 is 75 feet thick.

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal; lithified, dolomitic limestone and lithified dolomite

• "Porcelanite, dolomitic, gray, pale weathering; appears massive on fresh fracture but weathering reveals very fine lamination due to relief weathering of silty laminae; minor cross-lamination. Twelve feet below top is zone of fossiliferous buff dolomite. Near base is band of black chert nodules; a few inches higher is band with poorly sorted, rounded sand, dark chert granules and pebbles, and debris of silicified fossils, probably derived from underlying bed.
