Sequence Stratigraphic Framework of the Late Devonian (Frasnian) Duperow Formation in Western and Central Montana

“…Because of its proven oil and gas reservoir properties in the Alberta and Williston basins, the Duperow Formation has been extensively studied in these areas. The sequence stratigraphic framework is well documented (Day et al, 1996;Wendte & Uyeno, 2005;Cen, 2006;Cen & Hersi, 2009;Anna et al, 2010;Hopkins et al, 2010;Eggie et al, 2012;Alcorn, 2014;Gilhooly et al, 2014;Coleborne et al, 2015;Playton et al, 2016;Wong et al, 2016;Rogers, 2017;Bader, 2018). However, in western and central Montana, the Duperow Formation remains understudied.…”

“…Beginning in Early Devonian time, the ancestors to modern land plants evolved (McGhee, 1996;Dahl et al, 2010), Earth was in a greenhouse period (Joachimski et al, 2009;Wong et al, 2016), and Western North America was a passive margin (Dickinson et al, 1983;Dickinson, 2004). By Late Devonian (end Famennian) time, Earth had fully transitioned into an icehouse period (Streel et al, 2000;Brett et al, 2011), Western North America had experienced multiple glaciation events recorded in diamictites in South America (Caputo, 1984), carbonate belts had retreated to within 20 latitude of the equator compared to their prior 40 extent (Wendte et al, 1992), and the margin of Western North America had transitioned into an active tectonic regime with the Antler Orogeny beginning in Middle Devonian time (Burchfiel & Davis, 1972).…”
