Trilobites and Corals of the Blue Fiord Formation, Bathurst Island (Devonian of Canada)

Where: Nunavut, Canada (76.0° N, 99.0° W: paleocoordinates 8.7° S, 19.8° W)

• coordinate estimated from map

• basin-level geographic resolution

When: Blue Fiord Formation, Emsian (407.6 - 393.3 Ma)

• formation-level stratigraphic resolution

Environment/lithology: shallow subtidal; limestone and calcareous shale

• Some bioherms observed.

•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). "

• "On northern Bathurst Island, the B.F. Fm. consists of light to dark brown, finely crystalline, medium-bedded, fossiliferous limestone interbedded with brown, medium to coarsly crystalline, bioclastic limestone and grey calcareous shale."

Size class: macrofossils

Collection methods: Includes taxa not mentioned in measured sections.
