| Abstract | In this paper, a review of the current understanding of Devonian conodont biostratigraphy in the Mackenzie Mountains in the Northwest Territories is presented. The Devonian stratigraphy of the northern
and southern Mackenzie Mountains is presented on two chronostratigraphic charts, from the first deposits on top of the sub-Devonian unconformity to the lower part of the Imperial and Fort Simpson formations. Schematic maps give an overview of the
regional distribution of the formations in the Mackenzie Mountains. This update revealed that several of the assemblage and formation contacts are younger than presumed in an earlier time-stratigraphic chart; several formations and members are now
better constrained in the updated charts. The update also pointed out intervals in the charts for which no data were available and for which more research is needed to constrain formations in the Devonian conodont biozonation. |
| Summary | (Plain Language Summary, not published)
This manuscript deals with updating the relative geological ages of Devonian formations in the Mackenzie Mountains (North West Territories, Canada), from
the sub-Devonian unconformity to the Famennian (Upper Devonian) based on research done since the last overview in 1991 (Uyeno, 1991). Two charts present the northern and southern Mackenzie Mountain Devonian stratigraphy within the conodont biozones
framework. The zonation based on conodonts (a group of extinct marine organisms) is widely used and provides the most detailed zonation possible in the Paleozoic. Interpreted synthesis maps show the extent of the formations in the Mackenzie
Mountains. The update reveals that several of the Assemblage and formation contacts are younger than presumed in the time-stratigraphic chart by Uyeno (1991). Several formations and members are now better constrained in the chart. The update also
pointed out intervals in the charts where no data were available and more research is needed to constrain for |
