Baseline Investigations into the Groundwater Resources of the Athabasca Oil Sands (In Situ) Area, Northeast Alberta

Chapter 5 presents the results of a terrain analysis of the surficial geology, as determined by an aerial photograph interpretation of the landscape. Chapters 6 and 7 outline the bedrock topography and geology of the unconsolidated drift ... Show Abstract

Petrology and geochemistry of the Canadian Shield of northeastern Alberta

The remnant, central belt of granodioritic to quartz-monzonitic gneiss, of I-type granitoid composition, is flanked on its western argin by fairly homogeneous protons of biotite quartz monzonite to granite (Slave and Arch Lake Granitoids), and on ... Show Abstract

Geology of the basement beneath the Athabasca Basin in Alberta

The basement beneath the unconformity can be subdivided into four granitoid rock types recognized as part of the Wylie Lake pluton, and two mylonitic rock types derived partly from the granitoids and partly from a metasedimentary or metavolcanic ... Show Abstract

Polyphase Deformation in the Canadian Shield of Northeastern Alberta

Two generations of structures can be distinguished in the granite gneisses and intercalated high-grade metasediments of the basement neiss complex, which has been shown to be Archean by radiometry dating. In some areas, D2 folds form parts of domes ... Show Abstract

Polyphase Metamorphism in the Canadian Shield of Northeastern Alberta

During the Archean metamorphic cycle, metasediments were metamorphosed under high pressure granulite conditions (M1). Coexisting garnet-biotite and garnet-cordierite pairs in the metasediments allows estimation of P-T conditions during the ... Show Abstract

Geology of the Athabasca Group in Alberta

Abstract: Four formations of the Helikian Athabasca Group are present in Alberta. They are distinguished by variations in grain size, clay content and sedimentary structures. From the base, they are the Fair Point, the Manitou Falls, the Wolverine Point and the Locker Lake Formations. The Wolverine Point Formation is informally subdivided into an upper and a lower member.Petrographic studies of the Athabasca Group support the formational divisions and reveal a complex history of diagenesis. The diagenesis affected the porous units within the Athabasca Group and imparted to them a distinctive clay mineral composition that can be broadly elated to the lithostratigraphy. Thin section examinations reveal the uffaceous nature of many siltstones and shales of the upper member of the Wolverine Point Formation. These tuffs are both vitric and ash flow and are derived from a silica-over saturated volcanicity. The tuffs of the upper member of the Wolverine Point Formation show evidence of having been deposited under nearshore marine conditions; the remainder of the Athabasca Group was deposited in a fluvial setting.Areas of potential interest for uranium exploration occur where the Athabasca Group is less than 200 m thick and where it is present as outliers. Potential for economic lead-zinc mineralization is also present, associated with zones of fracturing in the sandstone.
