Outcrop of Upper Devonian – Lower Mississippian Tuttle Formation with Peel Plateau and Richardson Mountains in distance. Outcrop is located in northeastern part of NTS mapsheet 106L. View towards northwest.

The Yukon component of the study included portions of NTS map sheets 106L (Trail River), 106E (Wind River), 106F (Snake River) and 106K (Martin House).
From 2005 – 2009, Yukon Geological Survey geologists Tammy Allen and Tiffani Fraser were members of the multidisciplinary, collaborative four-year project in the Peel Plateau and Plain regions of the Yukon and Northwest Territories. The study, “Regional Geoscience Studies and Petroleum Potential, Peel Plateau and Plain, Northwest Territories and Yukon” involved participants from the Geological Survey of Canada, Northwest Territories Geoscience Office, Yukon Geological Survey, Carleton University, and the University of Alberta.

The primary objective of this study was to improve knowledge of regional geology, including stratigraphy and correlation, depositional and tectonic histories, basin evolution and petroleum geology and potential. 

Final deliverables from this project are two-fold and include:



Ninety additional publications are associated with this project. The full reference list is provided on pages 24-33 of the report.

YGS geologists concentrated their efforts on Upper Paleozoic strata in the Yukon portion of the Peel Plateau and in adjacent Richardson and Mackenzie Mountains. The main focus was to understand the Upper Devonian – Lower Mississippian Tuttle Formation, a chert and quartz-rich sandstone and conglomerate unit with alternating intervals of siltstone and shale. The stratigraphy, age, sedimentology, lithology, and hydrocarbon reservoir and source rock characteristics of the formation were refined as part of this study. Chapter 8 of the final volume, Upper Devonian to Carboniferous Strata II – Tuttle Formation Play, summarizes the study findings.
