Where: Nunavut, Canada (76.3° N, 99.0° W: paleocoordinates 8.5° S, 19.6° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Blue Fiord Formation, Emsian (407.6 - 393.3 Ma)
• "Unit n" [from bottom] is my terminology, not Ormiston's. Unit is 32 feet thick.
• group of beds-level stratigraphic resolution
Environment/lithology: shallow subtidal; limestone and dolomitic reef rocks
•SEP: From Rose (1999) Sedimentology and diagenesis of the lower Blue Fiord Formation carbonates in a prospective mississippi valley-type (Pb-Zn) setting, Bathurst Island, N.W.T. Univ. of Calgary MS thesis: "The Devonian Blue Fiord Formation (Emsian-Eifelian) consists of subtidal to supratidal carbonates deposited on a wide platform shelf. It is divided into three informal members based on facies associations; BF (sub 1) (Subtidal Restricted), BF (sub 2) (Lagoonal-Tidal Flat), and BF (sub 3) (Subtidal Open/Restricted). "
