Sub-project leaders: The purpose of this sub-project is to refine understanding of Athabasca stratigraphy and sedimentology, and their influence on mineralization. Depositional facies architecture, sequence stratigraphy, provenance and diagenesis will be determined for the entire basin with a focus on key areas such as Mc Arthur River, Midwest Lake, Dawn Lake, Rabbit Lake, Virgin River and Cluff Lake - Shea Creek which have good DDH coverage for core logging. Ramaekers' 1981 stratigraphic framework will be enhanced by the inclusion of DDH lithology, PIMA logs and geophysics. One object will be to integrate the geological maps for the Saskatchewan (Ramaekers, 1981) and Alberta (Wilson, 1985) parts of the Athabasca Basin, thereby eliminating the current apparent boundary fault. This work will be facilitated by the numerous drill holes which have been collared in basin over the past 20 years. The current stratigraphic model (illustrated below) will also probably be revised. Stratigraphic cross-section
The basal Manitou Falls Formation comprises mainly fluviatile sandstone and conglomerate. Overlying formations, except the uppermost Carswell Formation, are mainly shallow marine sandstone, pebbly sandstone, and mudstone. The Carswell Formation is stromatolitic and oolitic dolostone.
